try :mpirun -np 4 --hostfile [hostfilename] simpleFoam -parallel > log
also try: foamJob -p simpleFoam with the machines file in the system folder make sure all nodes have openFoam or can access OF functions. It could be your slave node 10.9.11.4 hasn't OF installed. see this for more info: http://www.cfd-online.com/Forums/ope...am-solved.html Last edited by longamon; April 28, 2011 at 12:15. |

i add [source /opt/openfoam171/etc/bashrc]
in the first line of these files sudo gedit ~/.Profile and gedit ~/.Bashrc and it worked SO if anyone have that kind of message then copy and paste the above line |
