How to make a roms model driven only by tidal and wave forcing

[zhaolv]

Hello, I have currently been able to successfully run the roms model as well as the wrf-roms-swan coupling model via coawst. However I find that I have to use a forcing file with wind fields in my roms model. How should I change my .h file if I want roms not to be driven by the wind field and only use the tidal forcing. And how do I set it up when roms and swan are coupled?

I don't know much about cpp options, but I tried turning off the BULK_FLUXES option and "define ANA_SMFLUX". I'm not sure if this is the right thing to do, but the result suggests that I need shflux data. The GFS data (including Uwind, Vwind, Pair, Tair, etc.) that I used when I "define BULK_FLUXES" did not include shflux data, and I would like to know where I need to download this data from.
