Dear RegCMers, I'm trying to run RegCM3 for a future Projection (2020=). The PreProcessing steps were run successfully, but when running the model, I remark a NaN values in some fields, for example:: " OUT-history written date =    2020042600.00000      BATS variables written at   2020042600  0.000000000000000E+000  Writing rad fields at ktau =          576  2020042600  BCs are ready from   2020042600   to   2020042606      at day =    1.0399, ktau =        600 :  1st, 2nd time deriv of ps =  NaN         NaN        ,  no. of points w/convection =       0  BATS variables written at   2020042603   180.000000000000          at day =    1.1267, ktau =        650 :  1st, 2nd time deriv of ps =  NaN         NaN        ,  no. of points w/convection =       0      at day =    1.2135, ktau =        700 :  1st, 2nd time deriv of ps =  NaN         NaN        ,  no. of points w/convection =       0            *** solar declination angle =  13.95 degrees.   dectim =    8640.00000000000   " Please help me if I have to change something in order to make a successful run Thank you very much in advance Sassi
