Hello RegCNET users,
I tried to run RegCM-4.4.5.10 with ERA-Interim mean for 10 years over tropical africa, but during model run an error appeared:

 CFL VIOLATION
 -------------------------------------------
 mod_tendency.F90 :     1590:            1
 Abort called by computing node            0 at 2016-01-25 13:18:46.337 +0100
--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI COMMUNICATOR 3 DUP FROM 0 
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.
I tried to decrease dt, but the error still exists, so do any one have an idea how to solve this problem?
I attached my namelist for my run.

Samy
