Question about WRF/WPS versions

[mlwasserstein]

I am trying to run a WRF simulation and successfully execute everything through real.exe, but when trying to run wrf.exe, my simulation crashes almost instantly. Here is the error message at the end of my rsl.error.0000 file:

forrtl: error (78): process killed (SIGTERM)

Clearly, there is not too much information here for me to detect what the problem may be.

My biggest suspicion, though is that it is due to differences in versions of WRF and WPS that I've been using.

I've taken geo_em* files that were created with wpsv4.2 and used those in wpsv4.5 to run ungrib and metgrid. And then I used wrfv4.5 to run real.exe and wrf.exe, before wrf.exe crashed almost immediately. I'm wondering if my differences in versions is the issue here. Are you required to use the same version of WRF and WPS throughout the entirety of the simulation process?

The difference in versions for WPS and WRF shouldn't be causing this problem. Can you attach your namelist.input file, as well as your WRF error/out log(s). If you have several rsl.* files, please package those together into a single *.tar or zipped file and attach that. Thanks!

 

[mlwasserstein]

Thanks for your help. My namelist.input file and rsl.* files are attached.

Thanks for sharing those. It's very likely that you'll need to use more processors to run this. Your domains are pretty large. You could easily use more than 500 processors. See Choosing an Appropriate Number of Processors. If it's still not working, then see What is the most common reason for a segmentation fault?, which discusses the model stopping immediately.
