Hi Hazari Syed!
I hope the problem you are getting has something to do with the "time step" 
in the namelist.input. Make sure that it is 6*the domain resolution in Km (6 
times the domain resolution in Km). 
My little experience show that even 3*the domain resolution sometimes can 
solve your problem.

Goodlucy
