[MITgcm-support] nonhydrostatic convection advice?

[Dustin Carroll]

Hi Scott,

I'll echo what Ryan and Yun said, the MITgcm works great for this type of application. Staggering the time step works well to help with stability. 

Cheers
Dustin

I would start from that tutorial and adapt it to your needs. You will probably want to use smagorinsky viscosities:
