I'm glad it finally works You might have experienced an Heisenbug
I don't remember right now, but probably there is something missing from the "test/parallel" application in OpenFOAM 1.6... probably misses an include to the PStream library, or something like that.

Tired of OpenFOAM-1.6? Do you want to experience new sensations with OF.1.6.x on Ubuntu? Here is the procedure. And do not forget to check this useful thread.
2. Disable OpenFOAM-1.6 environment: edit $HOME/.bashrc and delete the line
3. Download the wonderful script in openfoam-ubuntu.
4. Make the script executable and launch it:
$ chmod +x installOF.sh $ ./installOF.sh
5. Edit $HOME/.bashrc and add
alias startFoam16=". $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc" alias startFoam16x=". $HOME/OpenFOAM/OpenFOAM-1.6.x/etc/bashrc"
6. Periodically update OpenFOAM-1.6.x to the latest git version:
cd $WM_PROJECT_DIR git pull ./Allwmake >make.log 2>&1

I am working on interFoam/laminar/damBreak case. The number of cells in the generated mesh is 955000. To run in parallel, the mesh decomposition is done using metis decomposition.
When decomposed and running for 4 cores (quad-core Xeon E5620 ), it works perfectly fine.
On changing the decomposed case to 2-cores, After some time of running, the systems hangs and displays the following error: "mpirun noticed that process rank 0 with PID 3758 on node exited on signal 11 (Segmentation fault)."
Both of the cases (2-core and 4-cores) work fine for lower number of cells (< 600000 cells).
Please suggest. Thanks
