Dear,

I have installed lammps with poems package. But when I debug the examples of in.rigid.poems and in.rigid.poems2, the error appears as following. What’s the matter? would some kindy persons like to give some advice. Thanks in advance.

error:

It looks you are running examples/in.rigid.poems2 on a single proc.
When I do this, I don't get any errors, either MPI errors or when running
under a memory checker. Make sure you are running the
most current LAMMPS (fully patched). Also make sure
you can run other LAMMPS examples with your MPI, either
on 1 or more procs.

Is it failing immediately after setup, before any thermo info
is printed? Or is it failing at the very end of the run,
when MPI_Finalize() is called?
