MPI_ABORT when I run ./real.exe

[bernt]

wrf@DESKTOP-F0401I7:~/WRF/WRF/run$ ./real.exe
starting wrf task 0 of 1
--------------------------------------------------------------------------
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.

The error message in the rsl file is

As the message says, your namelist.input setting for num_metgrid_levels is 30, but the input (i.e., your met_em* files) only have a single level of data. Typically we would tell you to set the namelist to the value in the input, but you cannot run the model with only a single level. You will need to make sure your input data (prior to WPS) includes all required 3d atmospheric data, as well as surface data.
