[MITgcm-support] Re: routines to set geostrophically balanced initial conditions

[q li]

Nico,

What do these 4 options do in the model, especially MomStepping? In the beginning, do they use iteration or something else to get rid of ageostrophic movement?

I just did that recently, thanks to JMC and CNH, by setting

MomStepping=.TRUE.,
useCoriolis=.TRUE.,
MomAdvection=.FALSE.,
MomViscosity=.FALSE.,

in my data file. This way pretty much only geostrophy is left. nw
