[MITgcm-support] BC's for flow in a box

[David Hebert]

I would like to simulate a flow similar to an experimental setup of 
stratified fluid in a tank. In this configuration I would like to 
specify "closed" boundaries with a sponge layer. In order to do this, do 
I need to use OBCS prescribe to specify zero U,V at the boundaries (and 
corresponding T,S)? Or is it possible (and easier) by not specifying any 
open boundary indicies (that is, specify OB_Jnorth=nx*0, OB_Iwest=ny*0, 
etc.).

Thanks,


David
