[MITgcm-support] 2D setup

[Martin Losch]

Hi David,

no reply yet? I think this configuration should work, and I think that there are example setups like this, e.g. internal_wave
But since it crashes in the first step, it should be easy for you to debug. First step: set debugLev=2, and you'll get more model "statistics".

It seems that T/S are crashing after the first timestep (the U  continues to timestep). T/S are initialized good, but go to zero after 1st timestep. I'm wondering if I'm missing something regarding the obcs setup.
