Simulation stagnation during WRF 4.5 execution

[Sherry]

Dear all,
I am running WRF4.5. I have been running WRF since 0:00 on July 20, 2014. Everything was fine at first, but by 13:00 on July 22, there were no wrfout files generated. But I looked at the log file and there was nothing wrong.Could anyone give me some suggestions about this problem.Here attached my namelist.input and the error log file.
Kind regards,

Hi,
I don't see anything wrong with your namelist, and when I look in your rsl file, it shows that the wrfout* files are being written out. For e.g.,

Timing for Writing wrfout_d01_2014-07-20_00:00:00 for domain        1:   39.39214 elapsed seconds
Timing for Writing wrfout_d01_2014-07-20_01:00:00 for domain        1:   50.94360 elapsed seconds
Timing for Writing wrfout_d01_2014-07-20_02:00:00 for domain        1:  100.72024 elapsed seconds
Timing for Writing wrfout_d01_2014-07-20_03:00:00 for domain        1:   75.28247 elapsed seconds
Timing for Writing wrfout_d01_2014-07-20_04:00:00 for domain        1:   71.23319 elapsed seconds
Timing for Writing wrfout_d01_2014-07-20_05:00:00 for domain        1:   47.83147 elapsed seconds

Are you actually running WRF in the test/em_real directory (or even in run/)? If so, I would suggest discussing the issue with a systems administrator at your institution because I don't see anything wrong on the "wrf" side of things. I wish I had a better answer.

I have discussed this issue with the administrator. The problem is insufficient storage. I've deleted a lot of data files.But when I run wrf.exe again I get a CFL error.Here attached my namelist.input and the error log file.Could you give me some suggestions about this problem

I'm so glad you found the solution to the original problem! As for the CFL issue, it looks like you're already trying several of the suggestions mentioned in
What is the most common reason for a segmentation fault? It doesn't look like you tried the "smooth_cg_topo" suggestion, and it may not help, but can you give that a try? You also many have to try reducing your time step even more to see if that gets you past the issue.

I'm sorry to reply you so late. I tried "smooth_cg_topo" and unsurprisingly the simulation stalled. But when I type "grep cfl rsl*" there is no CFL error. The situation seems to get stranger.Here attached my namelist.input and the error log file.Could you give me some suggestions about this problem

I see that you're running WRF-Chem. Since this may be a WRF-chem issue, instead of a basic WRF issue, can you either post your question in the WRF-chem section of the forum, or if you'd like to try to run this test without chem, you can try that (with a basic WRF compile) and see if the problem is still evident. If so, will you open a new thread since the issue is no longer related to the original problem for this thread? This just helps to keep the topics easier to read and search through for other users. Thanks!
