[MITgcm-support] obcs_apply_ptracer

[Martin Losch]

Taka,

in spite of the long silence we haven't stopped thinking about you,  
if fact there has been quite some activity (o; As a result, I have  
checked in code that should fix your problem (but not in the way that  
you suggested):
You can now (after updating your code) set a flag OBCSfixTopo in  
data.obcs that will automatically change the topography so the it  
conforms to the requirements of OBCS, in other words, it will fill in  
topography along the boundary whereever it is deeper than in the next  
inward grid cell. Please try it out.
