[MITgcm-support] MOM_BOUNDARY_CONSERVE

[Christopher L. Wolfe]

Hi Jean-Michel,

I guess I'm just wondering if it's anything I need to worry about. I'm trying to do a momentum budget for a simulation and I'm having problems near the boundaries. 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.

There's also a note in mom_?_sidedrag.F about not getting the correct result for `thin' walls. Is one grid cell thin or thick?

Thanks,
Christopher
