Description

Good afternoon,
i'm running COAWST simulations with WRF+SWAN coupling, on different grids. I'm trying to compare the results with WRF standalone simulations to assess the importance of wind wave interactions.
I'm having issues with the WIND grid of SWAN. If i don't select it, the simulation runs smoothly, but when i postprocess the results, there is zero difference with WRF standalone simulations. When i add only INPGRID, without READINP, the simulation crashes. I attach here my swan input files, hoping to figure out the problem.
Thanks in advance for the help.

Research direction

Start by comparing the attached swan_Belgium.txt and swan_Belgium_ref3.txt input files, then reproduce the crash with INPGRID enabled without READINP in the WRF+SWAN setup. Done means identifying the input or coupling condition causing the crash and confirming that WIND-grid results differ appropriately from the WRF standalone case.
