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
