[Wrf-users] WRF 3.2 Model not running after 4hrs of Integration.

Thu Mar 3 21:32:04 MST 2011

Dear Sir, 
Thanks for the reply. I am running WRf 3.2 for the 3 domains 27, 9 and 3 km for the 48hrs Forecast on the IBM P570 Machine. The Operating system is AIX5.3 and the code is compiled using xlf with POE in place. 
I had given the command bash$ time poe ../wrf.exe -procs 8. 

1. The model gave segmentation fault after 4hrs of Integration. I also plotted the Model forecast for 2nd and 3rd hour at 27km resolution (Domain 1) So it showed me some data being plotted 
But when I tried to plot the output for the 2nd and 3rd domain, IT says ENTIRE GRID UNDEFINED. Kindly suggest.  

2. >>>What data I have used ??
I am using the .grib2 files as Initial and BC taken from ftp://ftpprd.ncep.noaa.gov.in at 1x1 degree resolution.  

3. >>>What is the error message in your output file? Did you find any CFL
    violation?  Your namelist.input looks fine. Please send us error messages in
    your run.
I am attatching the rsl.error* and the rsl.out* files, namelist.input and namelist.wps files. It seems to me that there is no CFL violation. 

Thanks.

    Geeta,

    What is the error message in your output file? Did you find any CFL
    violation? 

    Your namelist.input looks fine. Please send us error messages in
    your run.
