[MITgcm-support] exp0 with non-constant bathymetry

[Matthew Mazloff]

Hi Sergey,

If delZ=5000 then you have a single layer model.  To have the single 
layer vary with depth you have to use partial cells.  It sounds like 
partial cells are being used in your model but with a hfacmin and a 
hfacmindr that is smaller than you wish.  You should either change these 
values or add more layers.  Info on partial cells is in 2.10.7 of the 
manual.
