I am using RegCM 4.6 and doing experimental works related to CBMZ and DCCB chem type. The mpirun -np 1 ./bin/regcmMPI dcbc.in command shows the following msg for both experiments.

TUVGRID2 NOT FOUND

But the data was in /testing/CHEM_DATA

I am also attaching you the name list input file for your reference

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.

Need your help to overcome this error
