[MITgcm-support] One-column channel?

[Petter Stenström]

Hi,

I noticed that it is not possible to run a channel simulation with just
one column, i.e without supporting side-walls (e.g. nx*ny*nz = 100*1*10).
The salinity goes to zero in a few time steps, regardless of the initial
salinity. It's not a big problem, I can always add supporting side walls,
but I'm curious why the problem occurs. Any idea? Is the overlap
parameters (Oly, Olx) involved in some way? I've set them both to 1.
