[MITgcm-support] Error while creating bathymery : ini_masks_etc

[Camille Mazoyer]

Hi David,

Thanks for your reply.
My overlap are  OLx =  OLy =   3.
In fact, I wanted to have a netcdf grid file with mask values to prepare 
my OBC and my init state.
So usually I first run a simu without obc and init file to obtain a 
netcdf grid file with all informations (mask hfacc, ....), I then 
prepare my OBC + initial file.
Maybe It's not the right way to do it?

I understand that i=-2 and j=-2 can exist, because of OLx and OLy. But I 
think I have a problem with my depth or something else there because I 
have a floating invalid problem there.

If you have an idea of something to watch, or to verify?

Thanks a lot,
Camille
