Sponge Layer visc_factor

Hello, I'm trying to set a sponge layer in roms3.6 as described in this post https://www.myroms.org/projects/src/ticket/627. I have set LuvSponge == T ! horizontal momentum LtracerSponge == T T T ! temperature, salinity, inert The problem is Roms isn't reading visc_factor and diff_factor from my gri...

Re: Climatology as open boundary

Thank you for the replies.

I tried to put Rad instead of RadNud in order to use clm as boundary conditions, but it still asked for bry file. In there a way to use only clm file as boundary condition.

Thank you

Climatology as open boundary

Hi all, I'd like to know how to use only climatology file as open boundary (not nudging, as boundary conditions). Do I have to create a bry file too? If I have a bry and a clm file, which one is used as open boundary? My BC are: LBC(isFsur) == Clo Che Che Che ! free-surface LBC(isUbar) == Clo Shc Sh...

Re: Upwelling Channel with 4 Open Boundaries

I tried with grad = 0 in all boundaries and the domain energy kept rising (velocity rising) until my case blew up. Does anyone know if what I did is right, if I can't use grad to termohaline or something like that. Thank you in advance LBC(isFsur) == Gra Gra Gra Gra ! free-surface LBC(isUbar) == Gra...

Upwelling Channel with 4 Open Boundaries

Hi all, I'D like to know if there is a way to set up an upwelling channel case with four open boundaries (on the contrary of Roms' upwelling test case) and zero inflow and outflow current. I tried the following configuration, yet the wind generated current did not manage to radiate from the domain, ...

Hi Roms forum, I'm running a case in which my boundary conditions were built from my initial condition (initial_condition.png). It's a gausian current flowing along shelf break with 0 velocity elsewhere. The problem is I'm getting strong current velocities in the shallowest parts of my region (in th...
