Dear all          

 

                I have run RegCM 4.0 using NNRP2 data  for 90 km resolution and it gives good result. But when i used this 90 km output file as input for NEST run for 30 km the model gets stoped .

 

For run i have used MPI run using 16 processors on LINUX CENT OS cluster

 

Here i am giving  the error which came across to me  and also my regcm.in  -
