i am using roms in domain with one open boundary(in south) in tidal region for first time. before, i used rome in closed body without tide.
i don't know how can add tidal force to roms

by some posts it seems that tide is activated by SSH_TIDES and UV_TIDES options and requires a tide harmonic forcing netcdf file.is it correct?
would you please guide me that what harmonic forcing netcdf file should contain and in which dimensions?and how can provide it?
Many thanks for any reply
Cheers
