[RegCNET] NaN

[rajesh j]

Hello RegCM3 users,
Can anyone explain me what is meant by 'NaN', for
example my run below



*** solar declination angle =   9.75 degrees.
  dectim =    80640.0000000000
 OUT-history written date =    1998041418.00000
 BCs are ready from   1998041418   to   1998041500
     at day =   13.8003, ktau =       7950 :  1st, 2nd
time deriv of ps =  NaN        NaN        ,  no. of
points w/convection =       0
     at day =   13.8872, ktau =       8000 :  1st, 2nd
time deriv of ps =  NaN        NaN        ,  no. of
points w/convection =       0
     at day =   13.9740, ktau =       8050 :  1st, 2nd
time deriv of ps =  NaN        NaN        ,  no. of
points w/convection =       0



Why this happen? Is it my fault? Kindly spare a
response.
Thanks,
