[MITgcm-support] MOM_BOUNDARY_CONSERVE

[Jean-Michel Campin]

Hi Christopher,

I think this option (MOM_BOUNDARY_CONSERVE) will not do much with vertical 
wall (several levels high). 
The "thin wall" corresponds to a wall with no dry temperature point, 
so it does not apply to your case.

Cheers,
Jean-Michel

I noticed this routing, but I couldn't figure out if it was relevant in my case. I have straight vertical walls that are one grid cell thick, so nothing complicated.
