Error occurred after successfully simulating one-day wrfout while running wrf.exe: forrtl: severe (174): SIGSEGV, segmentation fault occurred

Hi there!

I am currently facing an issue while running wrf.exe. The program runs successfully, but after simulating the data for the first day, I encounter the following error. Any assistance would be greatly appreciated!

Specifically speaking, I am utilizing CMIP6 weather reanalysis data to simulate scenarios under different SSPs (Shared Socioeconomic Pathways). The data resolution is 1.25° with a temporal resolution of 6 hours. I configured three domains with resolutions of 25km, 5km, and 1km, respectively. The time_step is set to 90, and I am running the simulation using the command nohup mpirun -np 100 ./wrf.exe &.

I tried to simulate 2020-07-01 00:00:00 to 2020-07-04 00:00:00, with output every 6 hours. However, I am encountering the issue where I only obtain results for the period from 2020-07-01 00:00:00 to 2020-07-01 18:00:00.

I am attaching my namelist.input and rsl.error.0000 files for reference. Thank you in advance for any guidance!

Hi,
There are a couple of things I'd like you to try:

1) Since it seems to be stopping when you're writing the restart file, will you make the restart_interval larger to see if the model moves along further in that case?
2) If test 1 doesn't change anything, as another test, can you also try a single domain simulation to see if that runs to completion? If so, try two domains. This will help us to know which domain is causing the issue (if any).

Do you mind packaging all of your rsl* files into a single *.tar file and attaching that for us to take a look? Thanks!
 
Thanks a lot for your reply!
The first tip helped!

That is great news! Hopefully this is an okay option for you since you aren't running for very long.
