CMAQ seems to be aroused only once in coupled model

WRF-CMAQ
1

Hi all,

I used the WRFv45-CMAQv54 model to run a short test case. Running WRF alone went well, but when I ran the coupled model, the model aborted the second time it ran the CMAQ part, prompting a syntax error or segmentation fault. Like the subroutine
ADVSTEP or the module containing it did not start.

For example, my wrf_cmaq_freq = 5, then the model will stop after 10 WRF calculations and about to perform the second CMAQ calculation.

I tried to locate where the model stopped, add output token statements to the source code and compile it by ./compile em_real, but it didn’t work.

Here are my runscript and log files.If you have any ideas, please let me know to fix this problem.

Hi Fortuna,

I apologize for not replying your message sooner.

Base on the provided rsl.out.0000.txt, I am not able to determine the cause of the problem. Please send me all the rsl.* files. Thanks.

Cheers,
David
