Core Classes

Model

A model run.

It is intented to be model agnostic. It deals primarily with how the model is to be run, i.e. the period of the run and where the output is going. The actual configuration of the run is provided by the config object.

Further explanation is given in the rompy.core.Baseconfig docstring.

Config

pydantic model rompy.core.config.BaseConfig

Base class for model templates.

The template class provides the object that is used to set up the model configuration. When implemented for a given model, can move along a scale of complexity to suit the application.

In its most basic form, as implemented in this base object, it consists of path to a cookiecutter template with the class providing the context for the {{config}} values in that template. Note that any {{runtime}} values are filled from the ModelRun object.

If the template is a git repo, the checkout parameter can be used to specify a branch or tag and it will be cloned and used.

If the object is callable, it will be colled prior to rendering the template. This mechanism can be used to perform tasks such as fetching exteral data, or providing additional context to the template beyond the arguments provided by the user..

If this command is not used, SWAN will not\naccount for Bragg scattering.\n\nThe underlying process is related to the bed elevation spectrum that describes the\nrandom variability of the bathymetry at the scale of the wave length on top of a\nslowly varying depth. To input this spectrum in the model, two options are\navailable. One option is to read a spectrum from a file. This single bottom\nspectrum will subsequently be applied in all active grid points. The assumption\nbeing made here is that the inputted bottom is gently sloping. Note that the bottom\nspectrum must be given as a function of the wave number `k`.\n\nAnother option is to compute the spectrum by a Fourier transform from `x` to `k` of\nthe bed modulations around a computational grid point. First, one must define a\nsquare region with a fixed size around the grid point in order to perform the\nFourier transform. The size should correspond to a multiple of the wave length at\nwhich refraction is resolved (i.e. consistent with the mild slope assumption).\nNext, the amplitude modulation of the small-scale bathymetry is obtained by\nsubstracting a slowly varying bed level from the inputted high-resolution\nbathymetric data within this square region. Here, the smooth bed level is achieved\nusing a bilinear fit. During the computation, however, SWAN employs the gently\nsloping bed as the mean of the original bathymetry within the given square around\neach computational grid point. Finally, the corresponding bottom spectrum is\ncomputed with an FFT.\n\nNotes\n-----\nThe Bragg scattering source term to the action balance equation gives rise to a\nfairly stiff equation. The best remedy is to run SWAN in the nonstationary mode\nwith a relatively small time step or in the stationary mode with some under\nrelaxation (see command `NUM STAT [alfa]`).\n\nExamples\n--------\n\n.. ipython:: python\n    :okwarning:\n\n    from rompy.swan.components.physics import BRAGG\n    bragg = BRAGG(nreg=200)\n    print(bragg.render())\n    bragg = BRAGG(ibrag=1, nreg=200, cutoff=5.0)\n    print(bragg.render())",

But the diffraction approximation in SWAN does not properly handle\ndiffraction in harbours or in front of reflecting obstacles (see\nScientific/Technical documentation). Behind breakwaters with a down-wave beach, the\nSWAN results seem reasonable. The spatial resolution near (the tip of) the\ndiffraction obstacle should be 1/5 to 1/10 of the dominant wave length.\n\nNotes\n-----\nWithout extra measures, the diffraction computations with SWAN often converge\npoorly or not at all. Two measures can be taken:\n\n1. (RECOMMENDED) The user can request under-relaxation. See command `NUMERIC`\nparameter `alpha` and Scientific/Technical documentation (Eq. (3.31)). Very limited\nexperience suggests `alpha = 0.01`.\n\n2. Alternatively, the user can request smoothing of the wave field for the\ncomputation of the diffraction parameter (the wave field remains intact for all\nother computations and output). This is done with a repeated convolution filtering.\n\nExamples\n--------\n\n.. ipython:: python\n\n    from rompy.swan.components.physics import DIFFRACTION\n    diffraction = DIFFRACTION()\n    print(diffraction.render())\n    diffraction = DIFFRACTION(idiffr=True, smpar=0.0, smnum=1.0)\n    print(diffraction.render())",

By placing the obstacles close to\nthe shorelines SWAN will include the FIG source term along the coastlines\naccording to the parametrization of Ardhuin et al. (2014).\n\nThe location of the obstacle is defined by a sequence of corner points of a line.\nFor an obstacle line to be effective its length is at least one mesh size large. It\nis recommended to place the obstacles at the inner area of the computational grid,\nnot at or through the boundaries. In particular, each obstacle line must be\nbordered by wet points on both sides.\n\nIn addition, the orientation of the obstacle line determines from which side of the\nobstacle the FIG wave energy is radiated away. If the begin point of the line is\nbelow or left of the end point, that is, pointing upwards/to the right, then FIG\nenergy is radiated from the west/north side of the line. If the begin point is\nabove or right of the end point (pointing downwards/to the left), then FIG energy\nis radiated away from the east/south side of the obstacle line.\n\nReferences\n----------\nArdhuin, F., Rawat, A. and Aucan, J., 2014. A numerical model for free\ninfragravity waves: Definition and validation at regional and global scales.\nOcean Modelling, 77, pp.20-32.\n\nNotes\n-----\nEither `hss` or `tss` or both are allowed to vary over the computational domain.\nIn that case use the commands `INPGRID HSS` and `READINP HSS` and/or the commands\n`INPGRID TSS` and `READINP TSS` to define and read the sea-swell wave height/period\nIt is permissible to have constant sea-swell height and non-constant sea-swell\nperiod, or vice versa. The command `OBST FIG` is still required to define the\nobstacles. The values of `hss` and/or `tss` in this command are then not required\n(they will be ignored).\n\nExamples\n--------\n\n.. ipython:: python\n    :okwarning:\n\n    from rompy.swan.components.physics import OBSTACLE_FIG\n    obs = OBSTACLE_FIG(\n        alpha1=5e-4,\n        hss=2.5,\n        tss=10.3,\n        line=dict(xp=[174.1, 174.2, 174.3], yp=[-39.1, -39.1, -39.1]),\n    )\n    print(obs.render())\n    obs = OBSTACLE_FIG(\n        alpha1=5e-4,\n        hss=2.5,\n        tss=10.3,\n        reflection=dict(reflc=0.5),\n        line=dict(xp=[174.1, 174.2, 174.3], yp=[-39.1, -39.1, -39.1]),\n    )\n    print(obs.render())",

With the higher order schemes (S&L and SORDUP) it is important to use a\n  gradually varying grid otherwise there may be a severe loss of accuracy. If sharp\n  transitions in the grid cannot be avoided it is safer to use the BSBT scheme.\n* In the computation with unstructured meshes, a lowest order upwind scheme will be\n  employed. This scheme is very robust but rather diffusive. This may only be\n  significant for the case when swell waves propagate over relative large distances\n  (in the order of thousands of kilometers) within the model domain. However and\n  most fortunately, in such a case this will alleviate the garden-sprinkler effect.\n* Alleviating the garden-sprinkler effect by adding some diffusion makes the SWAN\n  computation conditionally stable. You can either use (i) a smaller time step,\n  (ii) a lower value of `waveage`, (iii) better resolution in the directional\n  space, or (iv) worse resolution in the geographic space, in order of preference,\n  to make the model stable when necessary.\n\nExamples\n--------\n\n.. ipython:: python\n    :okwarning:\n\n    from rompy.swan.components.numerics import PROP\n    prop = PROP()\n    print(prop.render())\n    prop = PROP(scheme=dict(model_type=\"bsbt\"))\n    print(prop.render())\n    prop = PROP(\n        scheme=dict(\n            model_type=\"gse\",\n            waveage=dict(delt=\"PT5H\", dfmt=\"hr\"),\n        ),\n    )\n    print(prop.render())",

Can be\nde-activated with command OFF QUAD. Note that the DIA approximation of the\nquadruplet interactions is a poor approximation for long-crested waves and\nfrequency resolutions that are deviating much more than 10% (see command CGRID).\nNote that DIA is usually updated per sweep, either semi-implicit (`iquad = 1`) or\nexplicit (`iquad = 2`). However, when ambient current is included, the bounds of\nthe directional sector within a sweep may be different for each frequency bin\n(particularly the higher frequencies are modified by the current). So there may be\nsome overlap of frequency bins between the sweeps, implying non-conservation of\nwave energy. To prevent this the user is advised to choose the integration of DIA\nper iteration instead of per sweep, i.e. `iquad = 3`. If you want to speed up your\ncomputation a bit more, than the choice `iquad = 8` is a good choice.\n\nExamples\n--------\n\n.. ipython:: python\n    :okwarning:\n\n    from rompy.swan.components.physics import QUADRUPL\n    quadrupl = QUADRUPL()\n    print(quadrupl.render())\n    kwargs = dict(\n        iquad=3, lambd=0.25, cnl4=3.0e7, csh1=5.5, csh2=0.833333, csh3=-1.25\n    )\n    quadrupl = QUADRUPL(**kwargs)\n    print(quadrupl.render())",

As the solution of a simulation approaches full\nconvergence, the curvature of the iteration curve will tend to zero. SWAN stops the\nprocess if the relative change in Hs from one iteration to the next is less than\n`drel` and the curvature of the iteration curve of Hs normalized with Hs is less\nthan `curvat` or the absolute change in Hs from one iteration to the next is less\nthan `dabs`. Both conditions need to be fulfilled in more than fraction `npnts`\npercent of all wet grid points.\n\nWith respect to the QC modelling, another stopping criteria will be employed.\nNamely, SWAN stops the iteration process if the absolute change in Hs from one\niterate to another is less than `dabs` * Hinc, where Hinc is the representative\nincident wave height, or the relative change in Hs from one to the next iteration\nis less than `drel`.

(2011). This damping is\nuniform over the wave frequencies. An alternative is the frequency-dependent\n(canopy) dissipation model of Jacobsen et al. (2019). If this command is not used,\nSWAN will not account for vegetation effects.\n\nThe vegetation (rigid plants) can be divided over a number of vertical segments and\nso, the possibility to vary the vegetation vertically is included. Each vertical\nlayer represents some characteristics of the plants. These variables as indicated\nbelow can be repeated as many vertical layers to be chosen.\n\nReferences\n----------\nDalrymple, R.A., Kirby, J.T. and Hwang, P.A., 1984.

bbox(buffer=0.0) → Bbox

Returns a bounding box for the spatial grid

This function returns a list [ll_x, ll_y, ur_x, ur_y] where ll_x, ll_y (ur_x, ur_y) are the lower left (upper right) x and y coordinates bounding box of the model domain

boundary(*args, **kwargs) → tuple

Returns the grid boundary polygon.

Override the parent method to use the actual points from the regular grid boundary instead of the convex hull which is not always the boundary.

boundary_points(spacing=None, tolerance=0.2) → tuple

Returns array of coordinates from boundary polygon.

Parameters:

• tolerance (float) – Simplify polygon shape based on maximum distance from original geometry, see https://shapely.readthedocs.io/en/stable/manual.html#object.simplify.

• spacing (float) – If specified, points are returned evenly spaced along the boundary at the specified spacing, otherwise all points are returned.

• Returns

• --------

• points (tuple) – Tuple of x and y coordinates of the boundary points.

dump_inputs_dict() → dict

Return the original inputs as a dictionary.

dump_inputs_json() → str

Return the original inputs as a JSON string.

classmethod from_component(component: GRIDREGULAR) → SwanGrid

nearby_spectra(ds_spec, dist_thres=0.05, plot=True)

Find points nearby and project to the boundary

Parameters:

• ds_spec (xarray.Dataset) –

  an XArray dataset of wave spectra at a number of points. Dataset variable names standardised using wavespectra.read_* functions.

  See https://wavespectra.readthedocs.io/en/latest/api.html#input-functions

• dist_thres (float, optional [Default: 0.05]) – Maximum distance to translate the input spectra to the grid boundary

• plot (boolean, optional [Default: True]) – Generate a plot that shows the applied projections

Returns:

A subset of ds_spec with lat and lon coordinates projected to the boundary

Return type:

get(destdir: str | Path, grid: SwanGrid | None = None, time: TimeRange | None = None) → Path

Write the data source to a new location.

Parameters:

• destdir (str | Path) – The destination directory to write the netcdf data to.

• grid (SwanGrid, optional) – The grid to filter the data to, only used if self.filter_grid is True.

• time (TimeRange, optional) – The times to filter the data to, only used if self.filter_time is True.

Returns:

cmd – The command line string with the INPGRID/READINP commands ready to be written to the SWAN input file.

Return type:

str

Note

The data are assumed to not have been rotated. We cannot use the grid.rot attr as this is the rotation from the model grid object which is not necessarily the same as the rotation of the data.

plot(param, isel={}, model_grid=None, cmap='turbo', figsize=None, fscale=10, borders=True, land=True, coastline=True, **kwargs)

Plot the grid.

property ds

Return the xarray dataset for this data source.

property outfile: str

rompy.swan.data.dset_to_swan(dset: Dataset, output_file: str, variables: list, fmt: str = '%4.2f', fill_value: float = -99.0, time_dim='time')

Convert xarray Dataset into SWAN ASCII file.

Parameters:

• dset (xr.Dataset) – Dataset to write in SWAN ASCII format.

• output_file (str) – Local file name for the ascii output file.

• variables (list) – Variables to write to ascii.

• fmt (str) – String float formatter.

• fill_value (float) – Fill value.

• time_dim (str) – Name of the time dimension if available in the dataset.

dump_inputs_json() → str

Return the original inputs as a JSON string.

get(destdir: str, grid: SwanGrid, time: TimeRange | None = None) → str

Write the data source to a new location.

Parameters:

• destdir (str | Path) – Destination directory for the SWAN ASCII file.

• grid (RegularGrid) – Grid instance to use for selecting the boundary points.

• time (TimeRange, optional) – The times to filter the data to, only used if self.crop_data is True.

Returns:

• filename (Path) – The filename of the written boundary file.

• cmd (str) – Boundary command string to render in the SWAN INPUT file

plot(model_grid=None, cmap='turbo', fscale=10, ax=None, **kwargs)

SWAN BOUNDSPEC SEGMENT data class.

TODO: Handle side definition on a rotated grid. TODO: Should SIDE VARIABE be supported? TODO: Support option to choose between mid-point or averaging? TODO: Does PAR need to be supported? Guess not as nonstationary isn’t supported TODO: If SIDES, ensure continuous

Note

Segments are defined from adjacent point locations so the order in which the points are defined is important. When using SIDES, please ensure SIDES are adjacent to each other and have correct directions (ccw or clockwise) accordint to the order in which each side is prescribed.

Note

The ‘spec1d’ file type is not supported yet.

This command must be entered immediately after a\n`COMPUTE` command.\n\nThe user may choose the format of the hotfile to be written either as free or\nunformatted. If the free format is chosen, then this format is identical to the\nformat of the files written by the `SPECOUT` command (option `SPEC2D`). This\nhotfile is therefore an ASCII file which is human readable.\n\nAn unformatted (or binary) file usually requires less space on your computer than\nan ASCII file. Moreover, it can be readed by a subsequent SWAN run much faster than\nan ASCII file. Especially, when the hotfile might become a big file, the choice for\nunformatted is preferable. Note that your compiler and OS should follow the same\nABI (Application Binary Interface) conventions (e.g. word size, endianness), so\nthat unformatted hotfiles may transfer properly between different OS or platforms.\nThis implies that the present and subsequent SWAN runs do not have to be carried\nout on the same operating system (e.g. Windows, Linux) or on the same computer,\nprovided that distinct ABI conventions have been followed.\n\nNote\n----\nFor parallel MPI runs, more than one hotfile will be generated depending on the\nnumber of processors (`fname-001`, `fname-002`, etc).\n\nExamples\n--------\n\n.. ipython:: python\n    :okwarning:\n\n    from rompy.swan.components.lockup import HOTFILE\n    hotfile = HOTFILE(fname=\"hotfile.swn\")\n    print(hotfile.render())\n    hotfile = HOTFILE(fname=\"hotfile.dat\", format=\"unformatted\")\n    print(hotfile.render())",

pydantic model rompy.swan.components.group.OUTPUT

Output group component.

FRAME 'sname' ...
GROUP 'sname' ...
CURVE 'sname' ...
RAY 'rname' ...
ISOLINE 'sname' 'rname' ...
POINTS 'sname ...
NGRID 'sname' ...
QUANTITY ...
OUTPUT OPTIONS ...
BLOCK 'sname' ...
TABLE 'sname' ...
SPECOUT 'sname' ...
NESTOUT 'sname ...

This group component is used to define multiple types of output locations and write components in a single model. Only fields that are explicitly prescribed are rendered by this group component.

Note

The components prescribed are validated according to some constraints as defined in the SWAN manual:

• The name ‘sname’ of each Locations component must be unique.

• The Locations ‘sname’ assigned to each write component must be defined.

• The BLOCK component must be associated with either a FRAME or GROUP.

• The ISOLINE write component must be associated with a RAY component.

• The NGRID and NESTOUT components must be defined together.

If this command is not used, SWAN will not\naccount for Bragg scattering.\n\nThe underlying process is related to the bed elevation spectrum that describes the\nrandom variability of the bathymetry at the scale of the wave length on top of a\nslowly varying depth. To input this spectrum in the model, two options are\navailable. One option is to read a spectrum from a file. This single bottom\nspectrum will subsequently be applied in all active grid points. The assumption\nbeing made here is that the inputted bottom is gently sloping. Note that the bottom\nspectrum must be given as a function of the wave number `k`.\n\nAnother option is to compute the spectrum by a Fourier transform from `x` to `k` of\nthe bed modulations around a computational grid point. First, one must define a\nsquare region with a fixed size around the grid point in order to perform the\nFourier transform. The size should correspond to a multiple of the wave length at\nwhich refraction is resolved (i.e. consistent with the mild slope assumption).\nNext, the amplitude modulation of the small-scale bathymetry is obtained by\nsubstracting a slowly varying bed level from the inputted high-resolution\nbathymetric data within this square region. Here, the smooth bed level is achieved\nusing a bilinear fit. During the computation, however, SWAN employs the gently\nsloping bed as the mean of the original bathymetry within the given square around\neach computational grid point. Finally, the corresponding bottom spectrum is\ncomputed with an FFT.\n\nNotes\n-----\nThe Bragg scattering source term to the action balance equation gives rise to a\nfairly stiff equation. The best remedy is to run SWAN in the nonstationary mode\nwith a relatively small time step or in the stationary mode with some under\nrelaxation (see command `NUM STAT [alfa]`).\n\nExamples\n--------\n\n.. ipython:: python\n    :okwarning:\n\n    from rompy.swan.components.physics import BRAGG\n    bragg = BRAGG(nreg=200)\n    print(bragg.render())\n    bragg = BRAGG(ibrag=1, nreg=200, cutoff=5.0)\n    print(bragg.render())",

But the diffraction approximation in SWAN does not properly handle\ndiffraction in harbours or in front of reflecting obstacles (see\nScientific/Technical documentation). Behind breakwaters with a down-wave beach, the\nSWAN results seem reasonable. The spatial resolution near (the tip of) the\ndiffraction obstacle should be 1/5 to 1/10 of the dominant wave length.\n\nNotes\n-----\nWithout extra measures, the diffraction computations with SWAN often converge\npoorly or not at all. Two measures can be taken:\n\n1. (RECOMMENDED) The user can request under-relaxation. See command `NUMERIC`\nparameter `alpha` and Scientific/Technical documentation (Eq. (3.31)). Very limited\nexperience suggests `alpha = 0.01`.\n\n2.

By placing the obstacles close to\nthe shorelines SWAN will include the FIG source term along the coastlines\naccording to the parametrization of Ardhuin et al. (2014).\n\nThe location of the obstacle is defined by a sequence of corner points of a line.\nFor an obstacle line to be effective its length is at least one mesh size large. It\nis recommended to place the obstacles at the inner area of the computational grid,\nnot at or through the boundaries. In particular, each obstacle line must be\nbordered by wet points on both sides.\n\nIn addition, the orientation of the obstacle line determines from which side of the\nobstacle the FIG wave energy is radiated away. If the begin point of the line is\nbelow or left of the end point, that is, pointing upwards/to the right, then FIG\nenergy is radiated from the west/north side of the line. If the begin point is\nabove or right of the end point (pointing downwards/to the left), then FIG energy\nis radiated away from the east/south side of the obstacle line.\n\nReferences\n----------\nArdhuin, F., Rawat, A. and Aucan, J., 2014. A numerical model for free\ninfragravity waves: Definition and validation at regional and global scales.\nOcean Modelling, 77, pp.20-32.\n\nNotes\n-----\nEither `hss` or `tss` or both are allowed to vary over the computational domain.\nIn that case use the commands `INPGRID HSS` and `READINP HSS` and/or the commands\n`INPGRID TSS` and `READINP TSS` to define and read the sea-swell wave height/period\nIt is permissible to have constant sea-swell height and non-constant sea-swell\nperiod, or vice versa. The command `OBST FIG` is still required to define the\nobstacles. The values of `hss` and/or `tss` in this command are then not required\n(they will be ignored).\n\nExamples\n--------\n\n.. ipython:: python\n    :okwarning:\n\n    from rompy.swan.components.physics import OBSTACLE_FIG\n    obs = OBSTACLE_FIG(\n        alpha1=5e-4,\n        hss=2.5,\n        tss=10.3,\n        line=dict(xp=[174.1, 174.2, 174.3], yp=[-39.1, -39.1, -39.1]),\n    )\n    print(obs.render())\n    obs = OBSTACLE_FIG(\n        alpha1=5e-4,\n        hss=2.5,\n        tss=10.3,\n        reflection=dict(reflc=0.5),\n        line=dict(xp=[174.1, 174.2, 174.3], yp=[-39.1, -39.1, -39.1]),\n    )\n    print(obs.render())",

Boundary

Boundary for SWAN.

pydantic model rompy.swan.components.boundary.BOUNDNEST1

Boundary spectra from a coarser SWAN nest.

BOUNDNEST1 NEST 'fname' ->CLOSED|OPEN

With this optional command a nested SWAN run can be carried out with the boundary conditions obtained from a coarse grid SWAN run (generated in that previous SWAN run with command NESTOUT). The spectral frequencies and directions of the coarse grid run do not have to coincide with the frequencies and directions used in the nested SWAN run; SWAN will interpolate to these frequencies and directions in the nested run (see Section 2.6.3). To generate the nest boundary in the coarse grid run, use command NGRID. For the nested run, use the command CGRID with identical geographical information except the number of meshes (which will be much higher for the nested run). This BOUNDNEST1 command is not available for 1D computations; in such cases the commands SPECOUT and BOUNDSPEC can be used for the same purpose. A nested SWAN run must use the same coordinate system as the coarse grid SWAN run. For a curvilinear grid, it is advised to use the commands POINTS or CURVE and SPECOUT instead of NGRID and NESTOUT.

Examples

In [1]: from rompy.swan.components.boundary import BOUNDNEST1

In [2]: boundary = BOUNDNEST1(fname="boundary.swn", rectangle="closed")

In [3]: print(boundary.render())
BOUNDNEST1 NEST fname='boundary.swn' CLOSED

pydantic model rompy.swan.components.boundary.BOUNDNEST2

Boundary spectra from WAM.

BOUNDNEST2 WAMNEST 'fname' FREE|UNFORMATTED ->CRAY|WKSTAT [xgc] [ygc] [lwdate]

With this optional command (not fully tested) a nested SWAN run can be carried out with the boundary conditions obtained from a coarse grid WAM run (WAM Cycle 4.5, source code as distributed by the Max Planck Institute in Hamburg). The spectral frequencies and directions of the coarse grid run do not have to coincide with the frequencies and directions used in the nested SWAN run; SWAN will interpolate to these frequencies and directions in the nested run (see Section 2.6.3). Note that SWAN will accept output of a WAM output location only if the SWAN grid point on the nest boundary lies within a rectangle between two consecutive WAM output locations with a width equal to 0.1 times the distance between these output locations on either side of the line between these WAM output locations. This BOUNDNEST2 command is not available for 1D computations. Only boundary conditions generated by WAM Cycle 4.5 can be read properly by SWAN. A nested SWAN run may use either Cartesian or spherical coordinates. A curvilinear grid may be used in the nested grid but the boundaries of this nest should conform to the rectangular course grid nest boundaries. WAM output files are unformatted (binary); this usually implies that WAM and SWAN have to run on the same computer. For those cases where WAM and SWAN run on different types of machines (binary files do not transfer properly), the option FREE is available in this command. The distributed version of WAM does not support the required free format nesting output; WAM users who modify WAM such that it can make formatted output, must modify WAM such that the files made by WAM can be read in free format, i.e. with at least a blank or comma between numbers.

Note

the contents of ‘fname’ file could look like:

CBO9212010000
CBO9212020000
CBO9212030000

pydantic model rompy.swan.components.boundary.BOUNDNEST3

Boundary spectra from WAVEWATCHIII.

BOUNDNEST3 WW3 'fname' FREE|UNFORMATTED ->CLOSED|OPEN [xgc] [ygc]

With this optional command a nested SWAN run can be carried out with the boundary conditions obtained from a coarse grid WAVEWATCH III run. The spectral frequencies and directions of the coarse grid run do not have to coincide with the frequencies and directions used in the nested SWAN run; SWAN will interpolate to these frequencies and directions in the nested run (see Section 2.6.3). The output files of WAVEWATCH III have to be created with the post-processor of WAVEWATCH III as output transfer files (formatted or unformatted) with WW_3 OUTP (output type 1 sub type 3) at the locations along the nest boundary (i.e. computational grid points in WAVEWATCH III). These locations are equal to the corner points of the SWAN nested grid and optionally also distributed between the corner points of the SWAN nested grid (the boundary of the WAVEWATCH III nested grid need not be closed and may cover land). The locations should be output by WAVEWATCH III in sequence (going along the nest boundary, clockwise or counterclockwise). Note that SWAN will accept output of a WAVEWATCH III output location only if the SWAN grid point on the nest boundary lies within a rectangle between two consecutive WAVEWATCH III output locations with a width equal to 0.1 times the distance between these output locations on either side of the line between these WAVEWATCH III output locations. This BOUNDNEST3 command is not available for 1D computations. A nested SWAN run may use either Cartesian or spherical coordinates. A curvilinear grid may be used in the nested grid but the boundaries of this nest should conform to the rectangular course grid nest boundaries.

pydantic model rompy.swan.components.boundary.BOUNDSPEC

Boundary along sides or segment.

BOUNDSPEC ->SIDE|SEGMENT CONSTANT|VARIABLE PAR|FILE

This command BOUNDSPEC defines parametric spectra at the boundary. It consists of two parts, the first part defines the boundary side or segment where the spectra will be given, the second part defines the spectral parameters of these spectra. Note that in fact only the incoming wave components of these spectra are used by SWAN. The fact that complete spectra are calculated at the model boundaries from the spectral parameters should not be misinterpreted. Only the incoming components are effective in the computation.

TODO: Add support for unstructured grid (k).

pydantic model rompy.swan.components.boundary.INITIAL

Initial conditions.

INITIAL -> DEFAULT|ZERO|PAR|HOTSTART

This command can be used to specify the initial values for a stationary (INITIAL HOTSTART only) or nonstationary computation. The initial values thus specified override the default initialization (see Section 2.6.3). Note that it is possible to obtain an initial state by carrying out a previous stationary or nonstationary computation.

Examples

pydantic model rompy.swan.components.physics.BRAGG

Bragg scattering.

BRAGG [ibrag] [nreg] [cutoff]

Using this optional command, the user activates a source term to represent the scattering of waves due to changes in the small-scale bathymetry based on the theory of Ardhuin and Herbers (2002). If this command is not used, SWAN will not account for Bragg scattering.

The underlying process is related to the bed elevation spectrum that describes the random variability of the bathymetry at the scale of the wave length on top of a slowly varying depth. To input this spectrum in the model, two options are available. One option is to read a spectrum from a file. This single bottom spectrum will subsequently be applied in all active grid points. The assumption being made here is that the inputted bottom is gently sloping. Note that the bottom spectrum must be given as a function of the wave number k.

Another option is to compute the spectrum by a Fourier transform from x to k of the bed modulations around a computational grid point. First, one must define a square region with a fixed size around the grid point in order to perform the Fourier transform. The size should correspond to a multiple of the wave length at which refraction is resolved (i.e. consistent with the mild slope assumption). Next, the amplitude modulation of the small-scale bathymetry is obtained by substracting a slowly varying bed level from the inputted high-resolution bathymetric data within this square region. Here, the smooth bed level is achieved using a bilinear fit. During the computation, however, SWAN employs the gently sloping bed as the mean of the original bathymetry within the given square around each computational grid point. Finally, the corresponding bottom spectrum is computed with an FFT.

Notes

The Bragg scattering source term to the action balance equation gives rise to a fairly stiff equation. The best remedy is to run SWAN in the nonstationary mode with a relatively small time step or in the stationary mode with some under relaxation (see command NUM STAT [alfa]).

If this command is not used, SWAN will not\naccount for Bragg scattering.\n\nThe underlying process is related to the bed elevation spectrum that describes the\nrandom variability of the bathymetry at the scale of the wave length on top of a\nslowly varying depth. To input this spectrum in the model, two options are\navailable. One option is to read a spectrum from a file. This single bottom\nspectrum will subsequently be applied in all active grid points. The assumption\nbeing made here is that the inputted bottom is gently sloping. Note that the bottom\nspectrum must be given as a function of the wave number `k`.\n\nAnother option is to compute the spectrum by a Fourier transform from `x` to `k` of\nthe bed modulations around a computational grid point. First, one must define a\nsquare region with a fixed size around the grid point in order to perform the\nFourier transform. The size should correspond to a multiple of the wave length at\nwhich refraction is resolved (i.e. consistent with the mild slope assumption).\nNext, the amplitude modulation of the small-scale bathymetry is obtained by\nsubstracting a slowly varying bed level from the inputted high-resolution\nbathymetric data within this square region. Here, the smooth bed level is achieved\nusing a bilinear fit. During the computation, however, SWAN employs the gently\nsloping bed as the mean of the original bathymetry within the given square around\neach computational grid point. Finally, the corresponding bottom spectrum is\ncomputed with an FFT.\n\nNotes\n-----\nThe Bragg scattering source term to the action balance equation gives rise to a\nfairly stiff equation. The best remedy is to run SWAN in the nonstationary mode\nwith a relatively small time step or in the stationary mode with some under\nrelaxation (see command `NUM STAT [alfa]`).\n\nExamples\n--------\n\n.. ipython:: python\n    :okwarning:\n\n    from rompy.swan.components.physics import BRAGG\n    bragg = BRAGG(nreg=200)\n    print(bragg.render())\n    bragg = BRAGG(ibrag=1, nreg=200, cutoff=5.0)\n    print(bragg.render())",

pydantic model rompy.swan.components.physics.DIFFRACTION

Wave diffraction.

DIFFRACTION [idiffr] [smpar] [smnum] [cgmod]

If this optional command is given, the diffraction is included in the wave computation. But the diffraction approximation in SWAN does not properly handle diffraction in harbours or in front of reflecting obstacles (see Scientific/Technical documentation). Behind breakwaters with a down-wave beach, the SWAN results seem reasonable. The spatial resolution near (the tip of) the diffraction obstacle should be 1/5 to 1/10 of the dominant wave length.

Notes

Without extra measures, the diffraction computations with SWAN often converge poorly or not at all. Two measures can be taken:

1. (RECOMMENDED) The user can request under-relaxation. See command NUMERIC parameter alpha and Scientific/Technical documentation (Eq. (3.31)). Very limited experience suggests alpha = 0.01.

2. Alternatively, the user can request smoothing of the wave field for the computation of the diffraction parameter (the wave field remains intact for all other computations and output). This is done with a repeated convolution filtering.

Examples

In [1]: from rompy.swan.components.physics import DIFFRACTION

In [2]: diffraction = DIFFRACTION()

In [3]: print(diffraction.render())
DIFFRACTION

In [4]: diffraction = DIFFRACTION(idiffr=True, smpar=0.0, smnum=1.0)

pydantic model rompy.swan.components.physics.NEGATINP

Negative wind input.

NEGATINP [rdcoef]

With this optional command the user activates negative wind input. This is intended only for use with non-breaking swell dissipation SSWELL ZIEGER. Parameter rdcoef is a fraction between 0 and 1, representing the strength of negative wind input. As an example, with [rdcoef]=0.04, for a spectral bin that is opposed to the wind direction, the wind input factor W(k, θ) is negative, and its magnitude is 4% of the corresponding value of the spectral bin that is in the opposite direction (i.e. in the wind direction). See Zieger et al. (2015) eq. 11, where a0 is their notation for [rdcoef]. Default [rdcoef]=0.0 and rdcoef=0.04 is recommended, though as implied by Zieger et al. (2015), this value is not well-established, so the user is encouraged to experiment with other values.

pydantic model rompy.swan.components.physics.OBSTACLE

Subgrid obstacle.

OBSTACLE ->TRANSM|TRANS1D|TRANS2D|GODA|DANGREMOND REFL [reflc] ->RSPEC|RDIFF &
    (FREEBOARD [hgt] [gammat] [gammar] QUAY) LINE < [xp] [yp] >

With this optional command the user provides the characteristics of a (line of) sub-grid obstacle(s) through which waves are transmitted or against which waves are reflected (possibly both at the same time). The obstacle is sub-grid in the sense that it is narrow compared to the spatial meshes; its length should be at least one mesh length.

The location of the obstacle is defined by a sequence of corner points of a line. The obstacles interrupt the propagation of the waves from one grid point to the next wherever this obstacle line is located between two neighbouring grid points (of the computational grid; the resolution of the obstacle is therefore equal to the computational grid spacing). This implies that an obstacle to be effective must be located such that it crosses at least one grid line. This is always the case when an obstacle is larger than one mesh length.

Notes

• The advise is to define obstacles with the least amount of points possible.

• SWAN checks if the criterion reflc^2 + trcoef^2 LE 1 is fulfilled.

In particular, each obstacle line must be\nbordered by wet points on both sides.\n\nIn addition, the orientation of the obstacle line determines from which side of the\nobstacle the FIG wave energy is radiated away. If the begin point of the line is\nbelow or left of the end point, that is, pointing upwards/to the right, then FIG\nenergy is radiated from the west/north side of the line.

pydantic model rompy.swan.components.physics.OBSTACLE_FIG

Obstacle for free infragravity radiation.

OBSTACLE FIG [alpha1] [hss] [tss] (REFL [reflc]) LINE <[xp] [yp]>

With this optional command the user specifies the obstacles along which the free infra-gravity (FIG) energy is radiated. By placing the obstacles close to the shorelines SWAN will include the FIG source term along the coastlines according to the parametrization of Ardhuin et al. (2014).

The location of the obstacle is defined by a sequence of corner points of a line. For an obstacle line to be effective its length is at least one mesh size large. It is recommended to place the obstacles at the inner area of the computational grid, not at or through the boundaries. In particular, each obstacle line must be bordered by wet points on both sides.

In addition, the orientation of the obstacle line determines from which side of the obstacle the FIG wave energy is radiated away. If the begin point of the line is below or left of the end point, that is, pointing upwards/to the right, then FIG energy is radiated from the west/north side of the line. If the begin point is above or right of the end point (pointing downwards/to the left), then FIG energy is radiated away from the east/south side of the obstacle line.

Notes

Either hss or tss or both are allowed to vary over the computational domain. In that case use the commands INPGRID HSS and READINP HSS and/or the commands INPGRID TSS and READINP TSS to define and read the sea-swell wave height/period It is permissible to have constant sea-swell height and non-constant sea-swell period, or vice versa. The command OBST FIG is still required to define the obstacles. The values of hss and/or tss in this command are then not required (they will be ignored).

pydantic model rompy.swan.components.physics.QUADRUPL

Nonlinear quadruplet wave interactions.

QUADRUPL [iquad] [lambda] [cnl4] [Csh1] [Csh2] [Csh3]

With this option the user can influence the computation of nonlinear quadruplet wave interactions which are usually included in the computations. Can be de-activated with command OFF QUAD. Note that the DIA approximation of the quadruplet interactions is a poor approximation for long-crested waves and frequency resolutions that are deviating much more than 10% (see command CGRID). Note that DIA is usually updated per sweep, either semi-implicit (iquad = 1) or explicit (iquad = 2). However, when ambient current is included, the bounds of the directional sector within a sweep may be different for each frequency bin (particularly the higher frequencies are modified by the current). So there may be some overlap of frequency bins between the sweeps, implying non-conservation of wave energy. To prevent this the user is advised to choose the integration of DIA per iteration instead of per sweep, i.e. iquad = 3. If you want to speed up your computation a bit more, than the choice iquad = 8 is a good choice.

pydantic model rompy.swan.components.physics.SCAT

Scattering.

SCAT [iqcm] (GRID [rfac]) (TRUNC [alpha] [qmax])

Using this optional command, the user activates a source term that allows for the generation and propagation of cross correlations between scattered waves due to variations in the bathymetry and mean currents. Such variations are rapid compared to the distancebetween the crossing waves (at the scale of 100-1000 m) and is particularly relevant for cases involving narrowband waves (swells) in coastal regions with shallow water and ambient currents. In turn, the immediate spatial effects of coherent scattering, interference, refraction and diffraction can cause large-scale changes in the wave parameters.

pydantic model rompy.swan.components.physics.SETUP

Wave setup.

SETUP [supcor]

If this command is given, the wave-induced set-up is computed and accounted for in the wave computations (during the computation it is added to the depth that is obtained from the READ BOTTOM and READ WLEVEL commands). This approximation in SWAN can only be applied to open coast (unlimited supply of water from outside the domain, e.g. nearshore coasts) in contrast to closed basin, e.g. lakes and estuaries, where this option should not be used. Note that set-up is not computed correctly with spherical coordinates.

Notes

• The SETUP command cannot be used in case of unstructured grids.

• Set-up is not supported in case of parallel runs using either MPI or OpenMP.

Examples

In [1]: from rompy.swan.components.physics import SETUP

In [2]: setup = SETUP()

pydantic model rompy.swan.components.physics.SICE

Sea ice dissipation.

SICE [aice]

Using this command, the user activates a sink term to represent the dissipation of wave energy by sea ice. The default method is R19 empirical/parametric: a polynomial based on wave frequency (Rogers, 2019). This polynomial (in 1/m) has seven dimensional coefficients; see Scientific/Technical documentation for details. If this command is not used, SWAN will not account for sea ice effects.

pydantic model rompy.swan.components.physics.SURFBEAT

Surfbeat.

SURFBEAT [df] [nmax] [emin] UNIFORM/LOGARITHMIC

Using this optional command, the user activates the Infragravity Energy Module (IEM) of Reniers and Zijlema (2022). Besides the energy balance equation for a sea-swell wave field, another energy balance is included to account for the transfer of sea-swell energy to the bound infragravity (BIG) wave. This infragravity energy balance also involves a nonlinear transfer, expressed by the biphase, through the phase coupling between the radiation stress forcing and the BIG wave. For the prediction of the biphase for obliquely incident waves, an evolution equation is provided under the assumption that the bottom slopes are mild and alongshore uniform.

pydantic model rompy.swan.components.physics.TURBULENCE

Turbulent viscosity.

TURBULENCE [ctb] (CURRENT [tbcur])

With this optional command the user can activate turbulent viscosity. This physical effect is also activated by reading values of the turbulent viscosity using the READGRID TURB command, but then with the default value of ctb. The command READGRID TURB is necessary if this command TURB is used since the value of the viscosity is assumed to vary over space.

pydantic model rompy.swan.components.physics.VEGETATION

Vegetation dumping.

VEGETATION [iveg] < [height] [diamtr] [nstems] [drag] >

With this command the user can activate wave damping due to vegetation based on the Dalrymple’s formula (1984) as implemented by Suzuki et al. (2011). This damping is uniform over the wave frequencies. An alternative is the frequency-dependent (canopy) dissipation model of Jacobsen et al. (2019). If this command is not used, SWAN will not account for vegetation effects.

The vegetation (rigid plants) can be divided over a number of vertical segments and so, the possibility to vary the vegetation vertically is included. Each vertical layer represents some characteristics of the plants. These variables as indicated below can be repeated as many vertical layers to be chosen.

pydantic model rompy.swan.components.physics.WCAPPING_KOMEN

Whitecapping according to Komen (1984).

WCAPPING KOMEN [cds2] [stpm] [powst] [delta] [powk]

Notes

The SWAN default for delta has been changed since version 40.91A. The setting delta = 1 will improve the prediction of the wave energy at low frequencies, and hence the mean wave period. The original default was delta = 0, which corresponds to WAM Cycle 3. See the Scientific/Technical documentation for further details.

Notes

• The scheme defaults to S&L and SORDUP for nonstationary and stationary simulations if not specified.

• All schemes (BSBT, SORDUP and S&L) can be used in combination with curvilinear grids. With the higher order schemes (S&L and SORDUP) it is important to use a gradually varying grid otherwise there may be a severe loss of accuracy. If sharp transitions in the grid cannot be avoided it is safer to use the BSBT scheme.

• In the computation with unstructured meshes, a lowest order upwind scheme will be employed. This scheme is very robust but rather diffusive. This may only be significant for the case when swell waves propagate over relative large distances (in the order of thousands of kilometers) within the model domain. However and most fortunately, in such a case this will alleviate the garden-sprinkler effect.

• Alleviating the garden-sprinkler effect by adding some diffusion makes the SWAN computation conditionally stable. You can either use (i) a smaller time step, (ii) a lower value of waveage, (iii) better resolution in the directional space, or (iv) worse resolution in the geographic space, in order of preference, to make the model stable when necessary.

Examples

In [1]: from rompy.swan.components.numerics import PROP

In [2]: prop = PROP()

In [3]: print(prop.render())
PROP

In [4]: prop = PROP(scheme=dict(model_type="bsbt"))

In [5]: print(prop.render())
PROP BSBT

pydantic model rompy.swan.subcomponents.startup.SPHERICAL

Spherical coordinates.

SPHERICAL [->CCM|QC]

Notes

projection options:

• CCM: central conformal Mercator. The horizontal and vertical scales are uniform in terms of cm/degree over the area shown. In the centre of the scale is identical to that of the conventional Mercator projection (but only at that centre). The area in the projection centre is therefore exactly conformal.

• QC: the projection method is quasi-cartesian, i.e. the horizontal and vertical scales are equal to one another in terms of cm/degree.

All coordinates of locations and geographical grid sizes are given in degrees;`x` is longitude with x = 0 being the Greenwich meridian and x > 0 is East of this meridian; y is latitude with y > 0 being the Northern hemisphere. Input and output grids have to be oriented with their x-axis to the East; mesh sizes are in degrees. All other distances are in meters.

Note that spherical coordinates can also be used for relatively small areas, say 10 or 20 km horizontal dimension. This may be useful if one obtains the boundary conditions by nesting in an oceanic model which is naturally formulated in spherical coordinates. Note that in case of spherical coordinates regular grids must always be oriented E-W, N-S, i.e. alpc=0, alpinp=0, alpfr=0 (see commands CGRID, INPUT GRID and FRAME, respectively).

This may be useful if one obtains the boundary\nconditions by nesting in an oceanic model which is naturally formulated in\nspherical coordinates. Note that in case of spherical coordinates regular grids\nmust always be oriented E-W, N-S, i.e. `alpc=0`, `alpinp=0`, `alpfr=0`\n(see commands CGRID, INPUT GRID and FRAME, respectively).\n\nExamples\n--------\n\n.. ipython:: python\n    :okwarning:\n\n    from rompy.swan.components.startup import SPHERICAL\n    coords = SPHERICAL()\n    print(coords.render())\n    coords = SPHERICAL(projection=\"qc\")\n    print(coords.render())",

• int or float, assumed as Unix time, i.e. seconds (if >= -2e10 or <= 2e10) or milliseconds (if < -2e10 or > 2e10) since 1 January 1970.

• ISO 8601 time string.

Note

The tdelta field can be specified as:

• existing timedelta object

• int or float, assumed as seconds

• ISO 8601 duration string, following formats work:

  • [-][DD ][HH:MM]SS[.ffffff]

  • [±]P[DD]DT[HH]H[MM]M[SS]S (ISO 8601 format for timedelta)

field form: str | None = None

A user-specified format string in Fortran convention, e.g., ‘(10X,12F5.0)’.Only used if format=’fixed’, do not use it if idfm is specified

Validated by:

• check_format_definition

field format: Literal['free', 'fixed', 'unformatted'] = 'free'

File format, one of ‘free’, ‘fixed’ or ‘unformatted’. If ‘free’, the file is assumed to use the FREE FORTRAN format. If ‘fixed’, the file is assumed to use a fixed format that must be specified by (only) one of ‘form’ or ‘idfm’ arguments. Use ‘unformatted’ to read unformatted (binary) files (not recommended for ordinary use)

Validated by:

SWAN boundary subcomponents.

pydantic model rompy.swan.subcomponents.boundary.CONSTANTFILE

Constant file specification.

CONSTANT FILE 'fname' [seq]

There are three types of files:

• TPAR files containing nonstationary wave parameters

• files containing stationary or nonstationary 1D spectra (usually from measurements)

• files containing stationary or nonstationary 2D spectra (from other computer programs or other SWAN runs)

A TPAR file is for only one location; it has the string TPAR on the first line of the file and a number of lines which each contain 5 numbers, i.e.: Time (ISO-notation), Hs, Period (average or peak period depending on the choice given in command BOUND SHAPE), Peak Direction (Nautical or Cartesian, depending on command SET), Directional spread (in degrees or as power of cos depending on the choice given in command BOUND SHAPE).

Note

Example of a TPAR file:

pydantic model rompy.swan.subcomponents.boundary.DEFAULT

Default initial conditions.

DEFAULT

The initial spectra are computed from the local wind velocities, using the deep-water growth curve of Kahma and Calkoen (1992), cut off at values of significant wave height and peak frequency from Pierson and Moskowitz (1964). The average (over the model area) spatial step size is used as fetch with local wind. The shape of the spectrum is default JONSWAP with a cos2-directional distribution (options are available: see command BOUND SHAPE).

pydantic model rompy.swan.subcomponents.boundary.HOTMULTIPLE

Hotstart multiple initial conditions.

HOTSTART MULTIPLE fname='fname' FREE|UNFORMATTED

Initial wave field is read from file; this file was generated in a previous SWAN run by means of the HOTFILE command. If the previous run was nonstationary, the time found on the file will be assumed to be the initial time of computation. It can also be used for stationary computation as first guess. The computational grid (both in geographical space and in spectral space) must be identical to the one in the run in which the initial wave field was computed

Input will be read from multiple hotfiles obtained from a previous parallel MPI run. The number of files equals the number of processors. Hence, for the present run the same number of processors must be chosen.

Examples

pydantic model rompy.swan.subcomponents.boundary.VARIABLEFILE

Variable file specification.

VARIABLE FILE < [len] 'fname' [seq] >

There are three types of files:

• TPAR files containing nonstationary wave parameters

• files containing stationary or nonstationary 1D spectra (usually from measurements)

• files containing stationary or nonstationary 2D spectra (from other computer programs or other SWAN runs)

A TPAR file is for only one location; it has the string TPAR on the first line of the file and a number of lines which each contain 5 numbers, i.e.: Time (ISO-notation), Hs, Period (average or peak period depending on the choice given in command BOUND SHAPE), Peak Direction (Nautical or Cartesian, depending on command SET), Directional spread (in degrees or as power of cos depending on the choice given in command BOUND SHAPE).

Note

Example of a TPAR file:

TPAR
19920516.130000 4.2 12. -110. 22.
19920516.180000 4.2 12. -110. 22.

Numerics

SWAN numerics subcomponents.

pydantic model rompy.swan.subcomponents.numerics.ACCUR

Stop the iterative procedure.

ACCUR [drel] [dhoval] [dtoval] [npnts] ->STAT|NONSTAT [limiter]

With this option the user can influence the criterion for terminating the iterative procedure in the SWAN computations (both stationary and non-stationary modes). SWAN stops the iterations if (a), (b) and (c) are all satisfied:

1. The change in the local significant wave height Hs from one iteration to the next is less than (1) fraction drel of that height or (2) fraction dhoval of the average Hs over all grid points.

2. The change in the local mean wave period Tm01 from one iteration to the next is less than (1) fraction drel of that period or (2) fraction dtoval of the average mean wave period over all wet grid points.

3. Conditions (a) and (b) are fulfilled in more than fraction npnts% of all wet grid points.

Note

This command has become obsolete in SWAN 41.01. The command STOPC should be used.

pydantic model rompy.swan.subcomponents.numerics.CSIGMA

Prevents excessive directional turning.

CSigma [cfl]

This option prevents an excessive frequency shifting at a single grid point or vertex due to a very coarse bathymetry or current locally. This option limits the frequency shifting rate csigma based on the CFL restriction. See also the final remark in Section 2.6.3. Note that if this command is not specified, then the limiter is not activated.

Examples

In [1]: from rompy.swan.subcomponents.numerics import CSIGMA

In [2]: csigma = CSIGMA()

In [3]: print(csigma.render())
CSIGMA

In [4]: csigma = CSIGMA(cfl=0.9)

pydantic model rompy.swan.subcomponents.numerics.STOPC

Stopping criteria of Zijlema and Van der Westhuysen (2005).

STOPC [dabs] [drel] [curvat] [npnts] ->STAT|NONSTAT [limiter]

With this option the user can influence the criterion for terminating the iterative procedure in the SWAN computations (both stationary and nonstationary). The criterion makes use of the second derivative, or curvature, of the iteration curve of the significant wave height. As the solution of a simulation approaches full convergence, the curvature of the iteration curve will tend to zero. SWAN stops the process if the relative change in Hs from one iteration to the next is less than drel and the curvature of the iteration curve of Hs normalized with Hs is less than curvat or the absolute change in Hs from one iteration to the next is less than dabs. Both conditions need to be fulfilled in more than fraction npnts percent of all wet grid points.

With respect to the QC modelling, another stopping criteria will be employed. Namely, SWAN stops the iteration process if the absolute change in Hs from one iterate to another is less than dabs * Hinc, where Hinc is the representative incident wave height, or the relative change in Hs from one to the next iteration is less than drel. These criteria must be fulfilled in more than npnts percent of all active, well-defined points.
