Error while running WRF-chem combined with Urban canopy model

[Kecheng Zhao]

Hello everyone, I encountered a problem while running WRF-Chem:

When I turn on the urban canopy model (sf_urban_physics=1), the WRF run suddenly stops at the step photolysis_driver: called for domain 2, and rsl.error.0000 does not output any specific error message. However, in other rsl.error files, I found:

forrtl: severe (174): SIGSEGV, segmentation fault occurred

But I have already added ulimit -s unlimited in my job submission script.

I did some additional tests:

1. When I turn off the urban canopy model (sf_urban_physics=0), WRF runs normally;
2. And when I turn on the urban canopy model (sf_urban_physics=1) but disable chemistry, WRF also runs normally.

This is very confusing to me. Please suggest.

Hello, may I ask if you have solved this problem? I have also encountered the same segmentation fault recently. Could you please offer me some assistance?
