[MITgcm-support] OBCS CPP flag

[Patrick Heimbach]

Hi Julie,

Dimitris' config. files are a very good starting point.

In particular, what was probably wrong in what you had is:

* need to add a line
obcs
in file packages.conf (this will enable the obcs package
and evaluate the obcs-specific options in OBCS_OPTIONS.h).

* don't put  #define ALLOW_OBCS in CPP_OPTIONS.h (not needed)

* check in OBCS_OPTIONS.h
whether the boundaries you'd like to be open are defined
(or otherwise undefined).

Some basic documentation is available at
http://mitgcm.org/r2_web_testing/latest/online_documents/node235.html

Cheers
-p.
