[RegCNET] Restart Run - 'NaN'

[Srivatsan Raghavan]

[Please ignore the earlier one..that was incomplete - Apologies]

Hi all,

I have been trying to do a restart run fro DJF 1991-92. The problem I have is
the 'NaN error ..

The  set of idates for the first run are :

'false'
idate0 = 1991120100
idate1 = 1991120100
idate2 = 1992010100          SAV  written :  SAV.1992010100

The set of idates for Restart I

'true'
idate0 = 1991120100
idate1 = 1992010100
idate2 = 1992020100          SAV written : SAV.1992020100

The set of idates for Restart II where I have problems:

'true'
idate0 = 1991120100
idate1 = 1992020100
idate2 = 1992022800

-----------------------
1. dx  from Domain is 40km
2. dt = 120 ; abatm = 360
-----------------------
1. I have checked for the input file for ICBC1992020100 ..It is complete and
fine and I am able to display all variables including 'ps'

2. Since the other restart worked fine, I guess the model did NOT crash because
of the 'dt' and 'abatm' values. I think they are Ok.. {??}

The run for Feb 1992 is fine and there is NO problem when it is NOT a restart.
The 'NaN' comes only during restart and the run hangs only on the dates -
1992020218 - 1992020300..

I have had the same problem occuring in the exact 2 and 3rd day in that month,
despite running it several times.


Any suggestions,

Thanks
