[MITgcm-support] MITgcm-support Digest, Vol 139, Issue 15

Thu Jan 15 12:17:57 EST 2015

hi martin and thank for your prompt reply,

yes my bathymetry H in some points (only in a few) equals the sum of my
delR.

may this affect the numerical outputs if I ask the model the velocity
fields in my last level?

cheers

marco
