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?
