[MITgcm-support] exp0 with non-constant bathymetry

[Samar Khatiwala]

Hi Sergey

Did you look at the Depth.data file that the model writes out? Does it
agree with your prescribed bathy? If not, this may have something to
do with hFacMin (in the data file). You probably want to set this to
a number < min(bathy)/delZ. Just a thought (and I could very well be
wrong!).
