Re: wave in coupling code

Hi, i have some question about the bottom roughness. When the d50 is very small, such as 0.005mm,the zo is very small, and it will take the minumum value 5e-5 in ssw_bbl. It will result in a large zeta. how to do it? increase the absolute_zoMIN ? The apparent bottom roughness have an impact on curre...

Hi,the MUD_POROS and MUD_TAU_CD are useless in the model ? ! Critical shear for erosion and deposition (N/m2). MUD_TAU_CD == 0.10d0 0.1d0 ! Porosity (nondimensional: 0.0-1.0): Vwater/(Vwater+Vsed). MUD_POROS == 0.5d0 0.9d0 I don't find them in the code, except in sedment_*.h. Thank you!

Thanks all!
If i add the nudging, the model need the temp/salt boundary file. I made a boundary file from the WOA monthly data, because of lacking observed data. It only one data per month.It can't meet my needs.
Have any other data or methods?

hi,
i know, in the tidal forcing file, the units of tide_Cangle is degree.
i don't know where units the conversion tide_Cangle to UV_Tangle.

when i add tide, the modle blow up . I find, maybe because the velocity too large.
I check the tide forcing file, there is nothing wrong in it. Why the model blow up ?
