Write spatial distributions.
BLOCK 'sname' ->HEADER|NOHEADER 'fname' (LAYOUT [idla]) < output > & [unit] (OUTPUT [tbegblk] [deltblk]) SEC|MIN|HR|DAYWith this optional command the user indicates that one or more spatial distributions should be written to a file.
Note
The SWAN special frames ‘BOTTGRID’ or ‘COMPGRID’ can be set with the sname field.
Note
The text of the header indicates run identification (see command PROJECT), time, frame or group name (‘sname’), variable and unit. The number of header lines is 8.
Note
Cannot be used in 1D-mode.

- Fields:
- Validators:
- field header: bool | None = None#
Indicate if the output should be written to a file with header lines (SWAN default: True)
- Validated by:
- field idla: IDLA | None = None#
Prescribe the lay-out of the output to file (supported options here are 1, 3, 4). Option 4 is recommended for postprocessing an ASCII file by MATLAB, however option 3 is recommended in case of binary MATLAB output (SWAN default: 1)
- Validated by:
- field model_type: Literal['block', 'BLOCK'] = 'block'#
Model type discriminator
- Validated by:
- field output: list[BlockOptions] [Required]#
The output variables to output to block file
- Constraints:
min_length = 1
- Validated by:
- field unit: float | None = None#
Controls the scaling of the output. The program divides computed values by unit before writing to file, so the user should multiply the written value by unit to obtain the proper value. By default, if HEADER is selected, value is written as a 5 position integer. SWAN takes unit such that the largest number occurring in the block can be printed. If NOHEADER is selected, values are printed in floating-point format by default (unit=1)
