read "Mesh_par_files" with the number of MPI processors is
"NPROC_XI*NPROC_ETA", and "xgenerate_databases" needs to read "Par_files"
with the numver of MPI processors is NPROC. But I find that
NPROC_XI*NPROC_ETA does not equal to  NPROC from the examples in the code in
most caes. Why?

So I always modified the parameter NPROC ,set it equal to NPROC_XI*NPROC_ETA
, go_mesher and go_generate_databases work ok.

But go_solver is always wrong like this:"
 need at least one receiver
 Error detected, aborting MPI... proc            0
 need at least one receiver
 Error detected, aborting MPI... proc            1
 need at least one receiver
 Error detected, aborting MPI... proc            2
 need at least one receiver
 Error detected, aborting MPI... proc            3
--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 3 in communicator MPI_COMM_WORLD
with errorcode 30.
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.
--------------------------------------------------------------------------
--------------------------------------------------------------------------
mpirun has exited due to process rank 3 with PID 19509 on
node node0975 exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).
--------------------------------------------------------------------------
[node0975:19475] 3 more processes have sent help message help-mpi-api.txt /
mpi-abort
[node0975:19475] Set MCA parameter "orte_base_help_aggregate" to 0 to see
all help / error messages
"

that is all. THank you
Best regards
