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
