Hi Hazari Syed!
May I appologize for the previous message. The message is correct if the core
in use is ARW (EM) but for NMM the time step in the namelist.input should be
2.25*(grid spacing in Km) or domain resolution in Km and/or about 330*(angular
grid spacing). 
I think this will solve your problem.
  
 Goodlucy

> >I have started using the new ARWpost program version 1.0, released on June
19.  In running ARWpost with the Intel compiler (ifort 9.1.043) on a Xeon
cluster, I have found three bugs that cause the program to crash.  (Curiously
no problems are indicated when using pgf90 on an Opteron cluster).

> >The bug is that real_array and real_domain point to the same target after
read_next_field is called once.  The first deallocate call will destroy the
target for both pointers.  Attempting to deallocate an unallocated target is
illegal in Fortran 90.

> >The bug is that several variables in the wrfout files have one character
names (e.g., "U", "V", "W").  For those variables, len_trim(cname) returns 1,
and the if statements try to evaluate cname(0:1), which is out of bounds.
