I have installed openFOAM4.0 and caelus7.04 versions on ubuntu 16.04. I could successfully run openFoam cases in parallel.

But, I am facing the following error when I try to execute my simulation in parallel on caelus7.04. can anyone help me how to execute my simulation in parallel?

It looks like orte_init failed for some reason; your parallel process is
likely to abort.  There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems.  This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):

  orte_session_dir failed

Hi vidyadhar, your error message appears to be identical to another user (Arka) that we have corresponded with via email. Their problem seemed to resolve itself.

Can you please confirm if your problem has been resolved or is still and issue?

Arka has somehow did it.
