Segmentation Fault

[hepan]

Hi, I run wrf.exe with 16 processors I get the following error:
===================================================================================
= BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES
= EXIT CODE: 139
= CLEANING UP REMAINING PROCESSES
= YOU CAN IGNORE THE BELOW CLEANUP MESSAGES
===================================================================================
YOUR APPLICATION TERMINATED WITH THE EXIT STRING: Segmentation fault (signal 11)
This typically refers to a problem with your application.
Please see the FAQ page for debugging suggestions

I attached the namelist and rsl.error files, can you help me please?

My sincere regards

Good molring @hepan

There are a lot of things that could be fixed in the namelist files that might be causing these errors. First thing I would do is go read over these best practices from NCAR for namelist.wps and namelist.input. I think if you make some slight changes based on their reccomendations you should fix your errors.

Also what is your input data source? I see that the domain is 3000x3000m. Depending on the data source you may need to do some nesting.

You also appear to be over some steep topography regions so I would make sure to check the WRF users guide page about the topography sections etac epssm

Thank you for your reply. My input data source is a 1° resolution file from NCEP-FNL. I will try to solve this problem according to your suggestion.

If I remember correctly 1°deg res is approximately 111km. So you will have to nest.

Make sure to read over the ratios sections. I can also send you the tutorials if you would like

Thank you. Please send me the tutorial. However, when I used two layers of nested meshes with a resolution of 3km and 1km, and geo_data_res=30s, my simulation worked. But after a few hours of running, the same error occurred again, so I reduced the time step and resumed running.

There are a few issues in your namelist.input:
(1) bl_pbl_physics = 0: for 3km run, you need to turn on PBL scheme
(2) num_soil_layers = 5: for Noah LSM< ythis number should be 4.
(3) is there any special reason you set ptop = 16161.1 ? Can you try otop = 5000?

Thank you for your advice. I will try to improve.
