[RegCNET] Problem in RegCM4.0 for NEST run.:

[pushpraj tiwari]

Dear all


           I have run successfully RegCM4.0 for 90 km using NNRP2 data. Now
i am trying to run with 30 km using 90 km output as icbc. Terrain and icbc
is running successfully and creating data.
           But when i am running the model using regcmMPI, i am getting
error which is shown below:




OPENING NEW SRF FILE: ./OUTPUT//SRF.2003110100

I am also attaching my regcm.in here:

I have also used dt = 20,15,10 when abatm = 300
also at dt =100 when  abtm = 600
But every time the same error comes.


Any help that you could give me, would be invaluable!




Thank you in advance
