[MITgcm-support] Equatorial Channel from -70 degree to +70 degree

[Yuan Lian]

Hi, Dimitris,

Thanks. I tried the configuration nPx=8, sNx=32, sNy=93 but the 
simulation gave NAN values. I had to reduce the number of grids in 
latitude. The configuration nPx=4, sNx=64, sNy=63 worked just fine. I 
will try nPx=4, sNx=64, sNy=93 and see how it works. I might try to use 
very short time step as well.

cheers,
Yuan
