Hello again,
I'm glad it finally works :) You might have experienced an Heisenbug :D 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. Quote:

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.
1. Backup! 2. Disable OpenFOAM-1.6 environment: edit $HOME/.bashrc and delete the line Code:
source $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc 3. Download the wonderful script in openfoam-ubuntu. 4. Make the script executable and launch it: Code:
$ chmod +x installOF.sh 5. Edit $HOME/.bashrc and add Code:
alias startFoam16=". $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc" 6. Periodically update OpenFOAM-1.6.x to the latest git version: Code:
cd $WM_PROJECT_DIR 8. Enjoy. |
Hi,
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 |
