Hi everyone,

im trying to get OpenFOAM to work in parallel on 2 nodes (each wich 16 cores).

for example, when i run foamjob -p -s simpleFoam, everything starts.
No error occurs, and on both machines the solver starts with 16 processes (listed in top).
this situation is not changing, while the output of foamjob is stuck:

Code:
Parallel processing using OPENMPI with 32 processors
Executing: /programme/OpenFOAM/OpenFOAM-3.0.x/ThirdParty-3.0.x/platforms/linux64Gcc/openmpi-1.10.1/bin/mpirun -np 32 -hostfile machines -x FOAM_SETTINGS /programme/OpenFOAM/OpenFOAM-3.0.x/bin/foamExec -prefix /programme/OpenFOAM simpleFoam -parallel | tee  log

Build  : 3.0.x-ebc9d688cb1a
Exec   : simpleFoam -parallel
Date   : Mar 04 2016
Time   : 22:10:38
Host   : "secret_host_1"
PID    : 14357
Does somebody has an idea whats wrong or what i've missed??

by the way, im using zsh and tmux, may this be a problem? i also tried it with a blank bash session; still the same...

Thanks in purpose!
