calculating parallel on two machines
Hi there,

maybe becaus of i am very new at open Foam i got a big problem.
i try to calculate on two different machines and i dont know how to synchronizes my 8 cores.
i think at this moment i am on the wrong way and i hope that someone could give me an interresting impulse :)

have you added the -parallel argument to the execution command?

For example a very simple execution command on 2 processors with pisoFoam looks like this:

mpirun -n 2 pisoFoam -parallel

For 2 different machines you should add a machine file as described in the user guide.

yep i startet a process succesfull with 4 cores on one machine... i think there can only be a very little aspect i have overlooked ....
Maybe in my decomposepardic file....
