[MITgcm-support] obcs/exf interactions

[Alistair Adcroft]

Resending msg:

I've mostly sorted out this upgrade of Tom's experiment from
ecco_c50_e29 to HEAD. The last problem has me puzzled - the attached
figure is of (U,V) and the difference between the two versions of the
model after just two steps using the same forcing/parameters.

The straight line is hard to see in the original fields and I can't
decide whether it comes from Tom's older code or is in the new model.
The line does not line up with tile boundaries (black grid in last
panel). The best I can determine is that the difference is something to
do with exf prescribing the OBC values. Various permutations of code led
me to this conclusion but I do not know which is right; I can only see
the line when I do a difference of outputs.

Anyone else seen a problem like this?

A.
