Polar WRF stops at day 2 00:30:00 of the run

[nikhilhale]

I am using WPS-4.2 and polar version of WRF 4.1.3. I pre-processed ERA5 data using WPS-4.2, obtained met_em* files and use those to run polar WRF-4.1.3 from model date Feb 01, 2013, 00:00:00. But on model date Feb 02, 2013 00:30:00, I encounter the following error.
Timing for main: time 2013-02-02_00:30:00 on domain 1: 0.54954 elapsed seconds
forrtl: severe (174): SIGSEGV, segmentation fault occurred

I have attached the met_em* files, rsl.error.0000, and the namelist.input.

Can you please help me figure out what's going wrong?

Hi,
There are several things that can cause segmentation faults and it can be tough to track down. First, have you tested this with standard WRF (i.e., not polar-wrf)? Polar-wrf if not developed/supported by our team, so we need to know if this same issue happens with basic wrf before we can address it.

If you are able to repeat the issue with basic WRF, then, if available, I'd like you to try to run this case with more processors. Can you try something like 36 processors and see if you can get further? If not, I'd like to see all of your rsl* files. Will you please package those together into a single *.tar file and attach that? Thanks!
