Hello all,
I'm running WRFV4.5 with sf_urban_physics=1 (i.e., SLUCM), unfortunately, the model stopped after integrating several hours. The error information which I got is as follows:
[ib0414:86410:0:86410] Caught signal 11 (Segmentation fault: address not mapped to object at address 0xfffffffe07e73c40)

I've looked up forums for solutions to segmentation fault, and set w_damping=1 and epssm=0.4. But these settings don't fix the error. However, when I turn off the urban mode (i.e., sf_urban_physics=0), the model is able to integrate continuously until the end time.
This confuses me, at this stage of WPS the static data I used is all default, I don't know why there is such a problem. Perhaps there is something in the latest version of WRF that needs to update the static files? I have attched my namelist and rsl files, I hope you can provide some help.
Thanks,
yuting
