[MITgcm-support] Turning off the ocean

[Chris Horvat]

Hey all,

I'd like to compare simulations with and without a dynamically active
ocean, but keeping the thermodynamic component. I've tried a couple of
methods that become unstable.

First I tried:

 saltAdvection = .FALSE.,
 tempAdvection = .FALSE.,

Which has worked for me in the past, but now goes unstable. So then I did
some more digging, and now set.

momForcing = .FALSE.,
momAdvection = .FALSE.,

But this also goes unstable after a while. Is there a way to totally turn
off the ocean momentum equations? I am using KPP + Smagorinsky viscosity.
Haven't turned them off yet in these unstable simulations as I am nervous
that this might introduce new issues.
