[MITgcm-support] boundary conditions, in general

[Haferman, Jeffrey (Jeff) (CIV)]

Hi -
I'm looking at exp5 supplied with MITgcm (imhomogeneously forced ocean
convection in a doubly-periodic box).

I've spent quite a bit of time looking through the documentation and the
input/data file, and it's not clear to me what settings are making the
lateral (x, y) boundary conditions to be periodic.  Can someone clarify?

Also, is it possible to make the boundary conditions periodic in the
vertical (z, or in the input code "r") dimension?  

Thanks,
Jeff
