[MITgcm-support] cal, exf, obcs: problem at the tile boundaries

[Nico Wienders]

Comrades,

I will bother you once again with one of my stupid questions
and, in advance, deeply apologize for making you waste your
precious time. But the truth is that i am actually stuck with an
error which i haven't been able to solve. It should be something
quite silly i assume.

In brief:

I am running an experiment with initial conditions, open boundaries
and climatological forcings. I get an error that my forcing fields have
incorrect values on the edge of the tiles, which is not true.
Any idea? Thank you. data.obcs, data.exf and SIZE.h are attached.
