[RegCNET] problem running model with 45 km resolution

[Satyaban Bishoyi Ratna]

Dear RegCM users,
  I am trying to make one month model integration with
45 km resolution and having 125 (N-S) and 144 (E-W)
grid points but I am not able to run it properly. I am getting
the error "...nan.....nan..." during run time of the model.
I tried with the timestep and other set up in 'regcm.in' as per
 the suggestion of RegCM document but it is not working.
Because as per the document the set up for 45 km resolution is
 radfrq  =    30.,
 abemh   =    18.,
 abatm   =   300.,
 dt      =   150.,
but it is not working.I tried the run with the changing number of
 'abatm' and 'dt' but no success.
When I tried the integartion with 60 km resolution with same domain
size, it works well.
Please tell me what is going wrong when I am trying to make 45 km
resolution. What are the things I need to change.
  Thanking you.

Best regards
Satyaban Bishoyi Ratna
