[RegCNET] Re : Re : Re : Undefined values in ECHAM Run!

[Bamba Sylla]

Hi,

dt is approximately 3*ds. Therefore, if your resolution is 60, 3*60=180 and if you still have NAN, you should decrease the dt again. So, i suggest you using:
dt=150
abatm=450

Hope it will help
Cheers !

Dear Sir,
The resolution is 60 km
The time steps are: abatm = 600 and dt = 200.
I'm working with 40 points only for this test.
The run message is like that:

OUT-history written date =    2020042500.00000     
 BATS variables written at   2020042500   3.33333333333333     
 Writing rad fields at ktau =            1  2020042500
     at day =    0.1134, ktau =         50 :  1st, 2nd time deriv of ps =  NaN         NaN        ,  no. of points w/convection =       0
 BATS variables written at   2020042503   180.000000000000     
     at day =    0.2292, ktau =        100 :  1st, 2nd time deriv of ps =  NaN         NaN        ,  no. of points w/convection =       0
           *** solar declination angle =  13.63 degrees.
  dectim =    2880.00000000000
