[RegCNET] Model Crashes even at lowest dt

[Mohamad Ibrahim OMAR]

Dear Syed,
First we need to know what is your resolution because this error came from the CFL creteria.
anyway if you use high resolution like 20 or 25 Km you should decrease the dt and also dtsrf. as the following;

  &timeparam

 dt     =   30.,   ! time step in seconds
 dtrad  =    30.,   ! time interval solar radiation calculated (minutes)
 dtabem =    18.,   ! time interval absorption-emission calculated (hours)
 dtsrf  =   120.,   ! time interval at which land model is called (seconds)

note that dtsrf = 3 dt
hope this helpfull.
Regards

I am running a simulation with RegCM-4.3.5.6 version and using CMIP5 GCM HadGEM2-ES historical data. The model run stops at a point after running 24 years and I get the following error. I have tried reducing the dt to lowest values (starting from 40 upto 5) but still the problem is same. 
Please advise!

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
