[Yan Libin]

Dear RCMers,

In regcm.in file of regcm4,
 /
  &chemparam
 idirect   =    0,
 inpchtrname  = 'SO2','SO4','BC_HB','BC_HL','OC_HB','OC_HL',
 inpchtrsol   =  0.10, 0.10, 0.10, 0.10, 0.20, 0.80, 0.05, 0.80, 0.05, 0.80
 inpchtrdpv(:,1) =0.,0.,0.,0., 0.00300,0.00200,0.00025,0.00025,0.00025,0.00025
 inpchtrdpv(:,2) = 0.,0.,0.,0., 0.00800,0.0020 ,0,0.00025,0.00250,0.00025,0.00250
 inpdustbsiz(:,1)  = 0.01
 inpdustbsiz(:,2)= 1.00
 /
While idirect=1 and idirect=2, it worked!
But when idirect=0, it failed!

  CFL VIOLATION
  -------------------------------------------
--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD 
with 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 on
exactly when Open MPI kills them.

How can I resolve it?
Thanks in advance!

Best regards,
Libin Yan
