Blowup with PE-NaN

run / config issues

I am running a simulation which blows up at a certain number of timesteps (after ~6 months of simulation) after the first initiation.

The logfile show PE and TotalE as NaN. Nothing wrong with KE.
Saving the output 1 step before the problem show nothing wrong or abnormal values for zeta,ubar,vbar etc.

So far I have tried:
-increasing/decreasing barotropic/baroclinic timesteps
-different forcing dataset
-different BC dataset

  • define/undef QCORRECTION
    The blowup is in the exact same time-step

Any ideas what could cause this problem?

Hi, is this a standard case or your own configuration?

The only thing I can think of is a problem with your boundary conditions/forcing file. How were they created?
