seg fault running OBSGRID with MADIS data

[Lily_Zh]

Dear Sir/Madam,​

I faced the same error shown below link. I am unsure if the segmentation fault is due to a too-large domain with high resolution (4km CONUS). I used OBSGRID for 12km CONUS before, no this error.
seg fault running OBSGRID with hourly data from MADIS

Thank you.

Hi Lily,
If you were to run WRF with the standard met_em* files (i.e., not using the OBSGRID program), does the model fail? If so, then the issue is likely not related to your obsgrid input, and I would request you to attach your namelist.input file, as well as the wrf error logs (e.g., rsl.error.* - please package all rsl* files into a single tar file and attach).

If it runs fine without using obsgrid, then please follow the steps requested in the post you referenced (running the default obsgrid namelist, and attaching the files requested, in addition to your obsgrid namelist). Thanks!

Hi Kwerner,
Thank you for your reply. I have the segmentation error when run obsgrid.exe, not WRF model.

Hi kwerner,

Thank you for your reply. I figured out the issue. I cannot run it on a login node, might be due to limited computing resource.

Thanks.
