Hello all,

I tried to extend the damBreak parallel tutorial to run it in two quad-core machines.

I have the same directories in both machines, ssh working without password.

I've set the decomposeParDict to 7 slaves.

The decomposePar command seems to work fine.

When I run the simulation (mpirun -np 8 --hostfile machines interFoam -parallel)
I got the message: "--> FOAM FATAL ERROR : Cannot find file "points" in directory "constant/polyMesh"

I've read some posts about it, but all of them were about the reconstruction. I've got it when trying to run the simulation...

Any suggestions?

Thanks in advance.

Hello vitors,

have you looked for the points in the constant/polyMesh directory? In case they don t exist, you should run blockMesh first, then decomposePar and finally mpirun...

Hi Matthias. I checked it and the files are there. But I could solve and (as usual when we are begginers) the problem was in decompositionParDict file. The roots were incorrect. I was using the case directory and when changed to the upper directory the simulation ran.

Thanks for your reply,
