[MITgcm-support] Open boundary conditions

Hi all,

I got a problem about a regional model with one open boundary. When the
prescribed OBC is used, the SSH continues to drop unless the OBCbalance is
set to be true. I guess there's some problem with the outflow, but I
checked the OB files, they all seem fine.

Is there any way to set the incoming flow as prescribed and outflow as
Orlanski radiation?  So the SSH would not drop so much.

Does anyone have similar problem? Thanks.
Xiangming
