Hi Radhaknata,

in order to get an idea about what causes this error I would need some more information about:
- the way esys-particle was invoked, i.e. using mpirun / mpiexec from the command line or via some queueing system (PBS, Torque, ...) , what parameters and so on
- the details of the system this was run on, in particular which OS and which version of MPI

This question was expired because it remained in the 'Needs information' state without activity for the last 15 days.

Still awaiting a response from OP

Although the OP provided little information to diagnose the problem, I suspect this error arose by invoking ESyS-Particle from within the Python Interpreter instead of using the "esysparticle" wrapper utility. This wrapper initializes MPI before loading the Python Interpreter and is mandatory for all ESyS-Particle simulation scripts.

Cheers,

Dion
