[MITgcm-support] Open Boundary Conditions in MITgcm

you might have noticed that the documentation of the obcs-pkg is incomplete:
but can find all the information about the OB_Ieast etc. indices and other run-time parameters. For more you'll have to consult the code in pkg/obcs and the corresponding experiments in verification I am afraid.
There is a orlanski-radiation conditions. To turn it on you need to re-compile with
in OBCS_OPTIONS.h and useOrlanskiNorth/South/East/West=.true. for the boundary of intererst. There are some experiments that use this option (e.g. tutorial_plume_on_slope, dome). If you are not happy with that, you'll need to implement something on your own.
I hope this helps,

This is the trivial task, because MIT gcm has internal waves verification example. It is necessary, what waves go through boundaries, but not reflect of that boundaries. How made it with obcs package or with other way? I made many experiments, but whitout positive results.
