[Mitgcm-support] Re: GMREDI test code

Patrick, is it true that to adapt the Sealion release GMREDI test code
to the ecco_env version,
all you have to do is change the links ?? 

The GMredi test case for Sealion release works as is (with deltaT=1800). 
But, with our configuration ( slope-limiter =  ldd97 , telescoping
grid, deltaT= 3600, etc.) it crashes.
