please read the swan manual.
the 999.. values tell swan those are land mask locations.
those 999.. values need to be the same as the Exception value you list in your swan.input file.

I am here to update the problem.
I believed that the problem happens in converting the grid from roms to swan.

I make roms grid and converted it to swan grid by roms2swan.m.
Then I used scrip_coawst_WW3SWAN.in for remapping and error in temp comes out.
When I run ./coawstM, the following error comes out.

MCT::m_ExchangeMaps::ExGSMapGSMap_:: MCTERROR, Grid Size mismatch
LocalMap Gsize = 9447 RemoteMap Gsize = 9514
MCT::m_ExchangeMaps::ExGSMapGSMap_: Map Grid Size mismatch error, stat =3
030.MCT(MPEU)::die.: from MCT::m_ExchangeMaps::ExGSMapGSMap_()

MCT::m_ExchangeMaps::ExGSMapGSMap_:: MCTERROR, Grid Size mismatch
LocalMap Gsize = 9514 RemoteMap Gsize = 9447

if you are using coawst, you can post a message here:
https://github.com/jcwarner-usgs/COAWST/issues

also i suggest you look at the Inlet_test case and the User manual for descriptions on how to set these up.

I'm running ROMS-SWAN model. I also have the same question. I set up my own application according to the Inlet_test case. Would you please give me any suggestions?
