[Wrf-users] wrf problem

[lee]

hi 
  I got a problem with wrf. I have run wrf model(showed 'wrf:SUCCESS COMPLETE WRF' in the end of the rsl.error.* and rsl.out.* files ) successfully for a 7-day simulation. And when I came to wrf2grads, it worked. When it finished, it showed 'GRACEFUL STOP'. the wrfout.ctl and wrfout.dat files were made by wrf2grads SUCCESSFULLY. But when I use grads to open wrfout.ctl, I try to display some variables. However, all the variables including U,V,W,HGT,Z with any level and any time were all undefined values. How can i deal with this problem. Can you help me? 
  I appreciate your reply.
