Issue with using pysph view

[phanindrasp]

I'm a beginner to pysph. I managed to install the package along with all the dependencies. Using the command "pysph run dam_break_2d" works for me and even prints the output data in the appropriate location. However, when I use pysph view dam_break_2d_output/, it throws up the following error:

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):

setting topology failed
--> Returned value Error (-1) instead of ORTE_SUCCESS

[phani-B85M-DS3H:7967] Local abort before MPI_INIT completed completed successfully, but am not able to aggregate error messages, and not able to guarantee that all other processes were killed!

FYI, I'm using mpirun (Open MPI) 2.1.1.
Any direction to debug this issue will be greatly appreciated :)

I am not clear as to what you are doing here. Are you using mpirun for pysph view? If so pysph view should be run as such without mpirun/mpiexec. The viewer runs as a single process without MPI.

No, I was just using the command "pysph view dam_break_2d_output/" or "pysph view" without mpirun. Not sure why this error pops up.
