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. <br /><br />basically, I was cutting my grids using a polygon I made which represented the land boundary.

Hi everyone am facing an issue with the wave module.<br /><br />Summary of the problem: <br /><em># Delft3D 4.04.01, MSWindows <br />#Delft3D-FLOW GUI, Version 3.59.01.57433, Aug 16 2018<br />#Deltares, Delft3D-WAVE GUI, Version 4.95.00.48953, Dec 13 2016,</em><br /><br /><br /><strong>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)<br />The midres.grd ( which works well on just flow module)<br />and inner_wave.grd(which crashes even if run standalone), most of my settings are the default for wave module.<br /><br />when run online coupled or standalone, these are the errors<br />Error: *** ERROR: SWAN file PRINT contains ERRORS<br />ERROR: *** ERROR: SWAN file PRINT contains ERRORS<br />Wave exited abnormally<br /><br />The error in the Print file is<br />Print file error : <br />3 comp. grid points on one line<br />Grid angle <0 or >180 degrees<br /><br />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. <br /> <br />What I tried, among other things:<br /><br />I tried using the same grid as midres.grd in the wave module, unfortunately, it still dint work <br />Also tried using a coarser version of the midres.grd in the wave module. <br /><br /><br />I am attaching my grid files and .mdw file below, if anyone could help out, would be great! thank you ! and Happy new year. </strong><br /> <br /><br />The ERROR snippet <br /><br /> $***************************** MODEL INPUT *****************************<br /> <br /> $<br /> <br /> SET LEVEL = 0.00 NOR = 90.00 DEPMIN = 0.05 _<br /> MAXMES = 1000 MAXERR = 2 _<br /> GRAV = 9.81 RHO = 1025.00 INRHOG = 1 _<br /> NAUT<br /> <br /> $<br /> <br /> MODE NONST<br /> <br /> CGRID CURV 44 56 EXCEPT 0.0 0.0 _<br /> CIR 36 0.05 1.00 24<br /> Resolution in sigma-space: df/f = 0.1329<br /> <br /> $<br /> <br /> READ COOR 1.
