Try to reduce the time step (say, to 100s), and see what happen.

Subject: [Wrf-users] model stops running after few minutes
Hello
I am trying to run the model for a nested configuration. However, my model stops running after few minutes!!! I found this to be present in all the three versions i. e. v3.3.1, v3.4.1 and v3.5. I think, I am doing something wrong. Please suggest something to overcome the issue. My namelist options are as follows:

Please note that I am using PGI compiler with gcc for compiling the model using dm+sm in open mpi linux x86_64 environment. I am not able to understand the exact problem. It looks like a run time issue. I feel I am not taking some namelist option in appropriate manner. However, I am not able to solve this.
Initially I tried with Milbrand MP but the model just stopped running after 1-2 mins. When I changed to Kesler MP, it ran for some time and then aborted. Again, after I changed the radt value from 20 to 30 mins it was running for some time more but again stopped on the way!
Please suggest something if possible.
Best regards
