[RegCNET] CFL Violation

[Mosuoe Letuma]

 Dear All.

May i kindly ask about the CFL Violation error. I am running for Southern
Africa Region using RegCM-4.0_clm. The simmulation completed successfully
for one month, but failed for 7 months with the CFL Violation error. My
regcm.in looks as follows:
 /
&dimparam
iy = 132,
jx = 128,
kz = 18,
nsg = 1,
/
&geoparam
iproj = 'NORMER',
ds = 50.0,
ptop = 5.0,
clat = -15.00,
clon = 30.00,
! plat = 30.00,
! plon = 115.00,
! truelatl = 30.0,
! truelath = 60,
/
 :
:
  /
 &timeparam
 radfrq  =    30.,
 abemh   =    18.,
 abatm   =   600.,
 dt      =   150.,
 ibdyfrq =          6,
 /

I also run the model for Africa, which was successful for 1990 and 1991,
but 1992, 1993 and 1995 gave me the error, CFL Violatio. The regcm.in was:
 /
&dimparam
 iy     = 180,
 jx     = 184,
  kz     = 18,
 nsg    = 1,
 /
 &geoparam
 iproj = 'NORMER',
 ds = 50.0,
 ptop = 5.0,
 clat = 0.00,
 clon = 18.00,
/

  The timeparam stanza was the same for the both domains. Upto this far, i
have not yet got the solutions to the previously posted problems regarding
the same error. May anyone help.

Kind Regards,
Letuma
