[MITgcm-support] Re: mdsio slice routines

[Matthew Mazloff]

Hi Suneet,

I have never checked.  I only use northern boundary.   I do not think  
there is a problem with your model set-up because you said the model  
runs.  Its the linesearch, optim.x, that doesn't work, correct?  So  
there is likely a bug or inconsistency in there somewhere...what  
error does the optimization give you?
