[Wrf-users] help on wrf.exe

Hi,

 

I am trying to run WRF4.0 model on high performance computing clusters.

After carefully setting up parameters in the namelist.input, as the program
is running on the clusters, sometimes I get the following error:

 

Program received signal SIGFPE: Floating-point exception - erroneous
arithmetic operation.

 

Backtrace for this error:

#0  0x7FBBFF295577

#1  0x7FBBFF295B8E

#2  0x7FBBFE6D426F

#3  0x14EB182 in __module_radiation_driver_MOD_radiation_driver

#9  0x46F70C in __module_integrate_MOD_integrate

#10  0x408263 in __module_wrf_top_MOD_wrf_run

 

 

Does anyone know the possible cause for the error message above? Also I
attached my namelist.input file here.

I say "sometimes I got the error message" because the program sometimes can
run successfully but sometimes give this type of error.

 

Thanks in advance!
