Hello everyone, I am trying to run the Fire module of WRF 4.2.2 using real data (GFS 0.25), and I get the the following error message after running wrf.exe: Timing for processing lateral boundary for domain 1: 0.02313 elapsed seconds Tile Strategy is not specified. Assuming 1D-Y WRF TILE 1 IS 1 IE 110 JS 1 JE 110 WRF NUMBER OF TILES = 1 FIRE:Time 1.500 s Average wind 0.108E+01 m/s FIRE:Time 1.500 s Maximum wind 0.313E+01 m/s FIRE:Time 1.500 s Fire area 0.000E+00 m^2 FIRE:Time 1.500 s Heat output 0.000E+00 W FIRE:Time 1.500 s Max heat flux 0.000E+00 W/m^2 FIRE:Time 1.500 s Latent heat output 0.000E+00 W FIRE:Time 1.500 s Max latent heat flux 0.000E+00 W/m^2 Timing for main: time 2024-01-22_01:00:01 on domain 1: 6.68451 elapsed seconds FIRE:crash: NaN detected -------------- FATAL CALLED --------------- FATAL CALLED FROM FILE: LINE: 152 crash: NaN detected I verified with ncview and qgis that "wrfinput_d01" file correctly contains the Anderson vegetation classification format for the domain, and the high resolution elevation for the fire grid also appears to be correct. Does anyone know what could be the cause, or how can I see the content of line 152?
