[Wrf-users] Segmentation faults, DX/DY, and timekeeping errors.

[Elliot]

Good afternoon,

I am running into a couple of problems while trying to run real-data, one-way nested w/ndown runs in both WRFV3.0 and WRFV3.1.1.  I am running a number of different cases, and while a good number of them will run and complete without a problem, there are a few that abort due to problems.  When those specific cases are repeated, they cut out at the same location due to the same problem.  An example of a problem I am having in WRFV3.0 is with ndown.exe, which is given as follows:

NDOWN_EM V3.0 PREPROCESSOR

Another problem I am having in WRFV3.0 is when trying to run the first child nest, after ndown.exe and real.exe have successfully completed.  Immediately upon the start of the first child WRF.exe, I get the following error:

Finally, I am running into problems with WRF.exe abruptly aborting in the middle of a run, ending with a segmentation fault.  Again, these segmentation faults occur in the exact same place when I attempt to repeat the same case.  The segmentation fault is given as follows:

b223:12055] *** Process received signal ***

Has anyone had any of these same issues, and if so what have you done to fix them?

Thanks,

Elliot.
