SWAN, WAVE module error with computational grid.
Youngling Posts: 4 Join Date: 5/26/21 Recent Posts
Hi everyone am facing an issue with the wave module.
Summary of the problem:
# Delft3D 4.04.01, MSWindows
#Delft3D-FLOW GUI, Version 3.59.01.57433, Aug 16 2018
#Deltares, Delft3D-WAVE GUI, Version 4.95.00.48953, Dec 13 2016,
I have two grids one finer midres.grd (450m-100m), which I use in the flow module and one coarse inner_wave.grd (4500m-950m) which I use in the wave module (obviously they lie in the same domain)
The midres.grd ( which works well on just flow module)
and inner_wave.grd(which crashes even if run standalone), most of my settings are the default for wave module.
when run online coupled or standalone, these are the errors
Error: *** ERROR: SWAN file PRINT contains ERRORS
ERROR: *** ERROR: SWAN file PRINT contains ERRORS
Wave exited abnormally
The error in the Print file is
Print file error :
3 comp. grid points on one line
Grid angle <0 or >180 degrees
Looking at the error it seems like there is something wrong in the computational grid and I cannot figure what it could be. When I created the grid, I took notice of all relevant properties (orthogonality, aspect ratio, smoothness and resolution) and stayed within limits (therefore I suppose the flow module worked well) am starting to think am missing something small and obvious here.
What I tried, among other things:
I tried using the same grid as midres.grd in the wave module, unfortunately, it still dint work
Also tried using a coarser version of the midres.grd in the wave module.
I am attaching my grid files and .mdw file below, if anyone could help out, would be great! thank you ! and Happy new year.

RE: SWAN, WAVE module error with computational grid.

To anyone that was looking for the answer, I solved it by simply not cutting my grids anymore for the wave module. I left the shadow region in, this eliminated the problem.
basically, I was cutting my grids using a polygon I made which represented the land boundary.
