Mud dumping.

MUD [layer] [rhom] [viscm]

With this command the user can activate wave damping due to mud based on Ng (2000). If this command or the commands INPGRID MUDLAY and READINP MUDLAY are not used, SWAN will not account for muddy bottom effects.

Examples

In [81]: from rompy.swan.components.physics import MUD

In [82]: mud = MUD()

In [83]: print(mud.render())
MUD

In [84]: mud = MUD(
   ....:     layer=2.0,
   ....:     rhom=1300,
   ....:     viscm=0.0076,
   ....: )
   ....: 

In [85]: print(mud.render())
MUD layer=2.0 rhom=1300.0 viscm=0.0076

TODO: Validate layer must be prescribed if INPGRID MUDLAY isn’t used.

Fields:

layer (float | None)
model_type (Literal['mud', 'MUD'])
rhom (float | None)
viscm (float | None)

field layer: float | None = None#: The thickness of the mud layer (in m). Note that layer is allowed to vary over the computational region to account for the zonation of muddy bottom. In that case use the commands INPGRID MUDLAY and READINP MUDLAY to define and read the layer thickness of mud. The value of layer in this command is then not required (it will be ignored)

field model_type: Literal['mud', 'MUD'] = 'mud'#: Model type discriminator

field rhom: float | None = None#: The density of the mud layer (in kg/m3) (SWAN default: 1300)

field viscm: float | None = None#: The kinematic viscosity of the mud layer (in m2/s) (SWAN default: 0.0076)

cmd() → str[source]#: Command file string for this component.
