[MITgcm-devel] status of OBCS changes

[Jean-Michel Campin]

Hi,

I have done most of the basic changes/cleaning I had in mind for OBCS.
(the last one was to bring the seaice advection/diffusion code 
 at the same level as T,S & pTracers).
I did not change anything in the seaice dynamics part with OBCS
(but I don't think wider-stencil schemes are used there,
 and don't know much about the solver/evp part).

Things that should now be possible is to move the OB further 
inside the domain (I tried with exp4) and to have concave
OB interior (not tried).

Going to make a checkpoint (62y) at some point (may be tomorrow ?)

A question to Matt: did you have a chance to update your 
code to check that it's still working with OBCS_CONTROL ?
(your simple test-exp is working, but not sure if I did not
 break things when splitting OBCS.h)

And to Martin: I can now turn off (or on) OBCSfixTopo, it 
does not change anymore the results of the verification tests.
We could think at some point to change the default to False,
but keeping the code as it is, in case we need it for a 
particular set-up.

Cheers,
Jean-Michel
