[MITgcm-support] A very strange problem

[Jean-Michel Campin]

Hi Dwight,

It would be help to have more details. For instance, parameter files
(data, data.pkg, and others data.*) as well as the few last lines of
the standard output & STDERR.* 
Right now, cannot tell much more.
Thanks,
Jean-Michel

In my model configuration, at first I set cofioris parameter f0=0, and that the initial V velocity to zero. In such a case the model is running well. However, when I change either of these  two parameters, (i.e., if I change f0=5e-5, or change initial V velocity to nonzero data which is from a previous run output), the model unreasonably stops at a specific iteration, for example,
