[MITgcm-support] Stopping execution when NaNs are generated?

[Martin Losch]

Jody,
has anyone answer you yet?
The CLF criterion is evaluated along with the monitor statistics. But  
in fact, the model is stopped if the monitor statistics encounter  
unrealistic temperature valures (something like +/- 1e4). So if you  
decrease your monitorFreq, the model will catch the problems before  
the large numbers have turned into nans (at the cost of very frequent  
monitor statistics).
