Hi,
I am a bit lost with the use of the sponge layer through visc_factor in the grid file.
Basically it modifies visc4 variable. But since i am using diffusive advection scheme i do not understand which values are in visc4 (which should be 0).
Any one could give me any insight about proper sponge setup?
Thanks
Xavier

I don't use the ROMS sponge feature. When the MOM6 people talk about sponges, they instead mean a nudging to a climatology around the edges of the domain. I do this kind of sponging instead.
