Greetings,

I am having problems to complete the MPPICFoam tutorial "cyclone".
It runs in parallel, but when reaches the time 1s, when the particles are beggining to be injected, it crashes.
If I run serial then it works.
I am trying to understand what is happening, but I could not find any similar question in the forum.
I am using Ubuntu 15.05 and openFoam 2.4.0.

--------------------------------------------------------------------------
mpirun has exited due to process rank 2 with PID 2254 on
node roger-desktop exiting improperly. There are two reasons this could occur:

1. this process did not call "init" before exiting, but others in
the job did. This can cause a job to hang indefinitely while it waits
for all processes to call "init". By rule, if one process calls "init",
then ALL processes must call "init" prior to termination.

2. this process called "init", but exited without calling "finalize".
By rule, all processes that call "init" MUST call "finalize" prior to
exiting or it will be considered an "abnormal termination"

This may have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).

The other MPPICFoam tutorials run fine in parallel.
Just this case didnt run, that, unfortunately is exactly the one I need.
Thanks for any help...

Did you get this resolved? I had the same problem at about 2 seconds.
