Dear Syed,
First we need to know what is your resolution because this error came from the CFL creteria.
anyway if you use high resolution like 20 or 25 Km you should decrease the dt and also dtsrf. as the following;
&timeparam
dt = 30., ! time step in seconds
dtrad = 30., ! time interval solar radiation calculated (minutes)
dtabem = 18., ! time interval absorption-emission calculated (hours)
dtsrf = 120., ! time interval at which land model is called (seconds)
note that dtsrf = 3 dt
hope this helpfull.

_______________________________________________I am running a simulation with RegCM-4.3.5.6 version and using CMIP5 GCM HadGEM2-ES historical data. The model run stops at a point after running 24 years and I get the following error. I have tried reducing the dt to lowest values (starting from 40 upto 5) but still the problem is same.Please advise!AhsanCalculate solar declination angle at 1994041600JDay 105.00 solar declination angle = 10.35514687 degreessolar TSI irradiance = 1367.0000 W/m^2SEARCH BC data for 1994041606READY BC from 1994041600 to 1994041606mod_tendency.F90 : 1434: 1MAXVAL ATEN U : 0.23073690760361867II : 111 , JJ : 26 , KK : 3MAXVAL ATEN QV : 4.6023637038836721E+023MAXVAL ATEN U : 0.21479913170870082II : 170 , JJ : 171 , KK : 13MAXVAL ATEN QV : 1.0977250150088500E+058MAXVAL ATEN T : 1.5864251565803420E+056MAXVAL ATEN U : 4.1836639784397066E+110MAXVAL ATEN V : 7.3548874512758020E+111MAXVAL ATEN QV : 4.4003993185280386E+052MAXVAL ATEN QC : 7.7744572396704626E+052MAXVAL ATEN U : 0.71302511089845821II : 169 , JJ : 163 , KK : 23MAXVAL ATEN V : 0.25478128763041386II : 169 , JJ : 148 , KK : 12MAXVAL ATEN T : 0.85502878291439455MAXVAL ATEN T : 0.70550992717408301II : 159 , JJ : 201 , KK : 23MAXVAL ATEN V : 0.27443318054567201II : 105 , JJ : 199 , KK : 7MAXVAL ATEN T : 0.74070002849556327II : 139 , JJ : 203 , KK : 23MAXVAL ATEN U : 0.66880242640804233II : 137 , JJ : 199 , KK : 23MAXVAL ATEN V : 0.23854246733191675II : 127 , JJ : 197 , KK : 9MAXVAL ATEN U : 0.71785515648095088II : 164 , JJ : 206 , KK : 23MAXVAL ATEN V : 0.26687884044440968II : 167 , JJ : 206 , KK : 8II : 116 , JJ : 200 , KK : 23MAXVAL ATEN U : 0.28197099267345371II : 119 , JJ : 202 , KK : 8MAXVAL ATEN V : 0.31751600673955133II : 113 , JJ : 202 , KK : 8--------------------------------------------------------------------------MPI_ABORT was invoked on rank 63 in communicator MPI_COMM_WORLDwith errorcode 1.NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.You may or may not see output from other processes, depending onexactly when Open MPI kills them.--------------------------------------------------------------------------ATM variables written at 1994-04-16 00:00:00 UTCSRF variables written at 1994-04-16 00:00:00 UTCSTS variables written at 1994-04-16 00:00:00 UTCRAD variables written at 1994-04-16 00:00:00 UTCWHUUUUBBBASAAAGASDDWD!!!!!!!!!!!!!!!!No more atmosphere here....CFL violation detected, so model STOP###################################### DECREASE DT !!!! ######################################
