[RegCNET] CFL Violation

[Azar Zarrin]

Dear all,

I'm running a parallel RegCM4 simulation for a 3-month period and the model
stops at the 54th day of my simulation giving the CFL violation error.
The horizontal resolution of the domain is 20km and I set the following time
parameters for my simulation.

 radfrq  =    30.,
 abemh   =    18.,
 abatm   =   120.,
 dt      =    60.,

Then, I decreased the dt to 40 and ran again. The run time dramatically
increased but the model stopped at the same date.

Any suggestion to resolve this problem would be appreciated.

Thank you,
Azar
