Dear colleagues,
I'm running wrf-fire with WRFV3.9, and everything's going well except the final step with the ./wrf.exe. The wrf.exe ran for about 21 hours fluently and then crashed suddenly with the error message saying:

FIRE:crash: prop_ls: increase the fire region
-------------- FATAL CALLED ---------------
crash: prop_ls: increase the fire region

I'm not sure if this message means I have to enlarge the fire_ignition_radius1 in namelist.input. But I've tried fire_ignition_radius1=40,100, and 200, and it seems that wrf.exe crashed at the same place for the same reason. I've no idea what parameter to adjust now. :? I have my rsl.error file, namelist.wps, namelist.input files attached. Thank you so much for helping! :D

Best regards,

Hi Xuelin,
Are you trying to run a real-data case to simulate wild fire? If so, please find relevant information at the website here: We no longer maintain and support WRF-FIRE.
