The wrf.exe stops running

[sekluzia]

Dear Colleges,

The wrf.exe stops running at 45 min forecast step. I am not able to understand where is the error, because there is no information on any error in my rsl.error file (attached). Could you look that file and tell me what is the paroblem?
Please note, that before running the wrf.exe I added random noise to the initial and lateral boundary conditions using WRFDA RANDOMCV capability. The failure in running occurs when the updated wrfinput_d01, wrfinput_d02 and wrfbdy_d01 files are used. I updated both wrfinput_d01 and wrfinput_d02 (by da_wrfvar.exe) and wrfbdy_d01 (by da_update_bc.exe) before running the wrf.exe.

Best regards,
Artur

Hi,
Have you tried this without making any modifications to the IC/BC files with WRFDA? I'm asking to determine whether this is a WRF or a WRFDA issue. If it happens even when you don't update the IC/BC files, then this is likely a WRF problem, but otherwise, it's likely related to something that occurs with the WRFDA/RANDOMCV utility and I will need to move this post to the WRFDA section to see if they can help.

Thanks for your reply! This problem did not occur without making any modifications to the IC/BC files.
Today I reduced time_step from 60 to 45 (dx=9km) and it started to work.

Artur,
That's great! I'm glad to hear you were able to correct it. If you run into any more problems with this, and it seems to be specific to a WRFDA utility/program, please post the new question in the WRFDA section of this forum so that a member of their team can help you.
