fort.15 configuration for NWS13

required changes

  ·   1 min read

ADCIRC>=v55 is required in order to use the NWS=13

Parameters #

NWS : set to 13 or the equivalent if coupling to SWAN, etc.

WTIMINC : configurable grid-to-mesh interpolation timestep in seconds, separate from the input data timesteps. If the file contains storm-following grids, there may be some utility in setting this finer than the input timestep(s).

If running the padcswan coupled ADCIRC+SWAN model, the wave coupling timestep can also be included here, as is normally done.
