Hello,
I am running a ROMS-SWAN coupled model using COAWST. Something very weird happened when I ran a new case today. When I loaded and plotted h from a history file, I found out that for some reason, the left side boundary depth has been flipped with the right side boundary depth. In my case, the left side is ocean and the right side is land. Since they have been flipped, the left side of my model becomes a wall(mask is flipped too). So nothing goes through....
I have checked my input grid.nc file and it looks fine. I have used it to run a ROMS only case and it worked out fine. I have used it to run a ROMS-SWAN model on a different area (Except for the input files, everything else are the same) and it worked out fine.
Any suggestion will be appreciated!
Best,
Tongtong
Boundary Flipped Problem
Re: Boundary Flipped Problem
It sounds like you have somehow turned on east/west periodic boundary conditions. What are your LBC values?
