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... Greetings, matthias |

Hello All,
I am new to openFoam. I am facing some issues on running in parallel. The first attempt was in trying to run the dambreak tutorial. got the below error: -------------------------------------------------------------------------------------------------------------- Primary job terminated normally, but 1 process returned a non-zero exit code. Per user-direction, the job has been aborted. -------------------------------------------------------------------------------------------------------------- The way I ran the solver is by typing in the terminal: mpirun -np 4 interFoam -parallel The second attempt is when I tried to ran lockExchange tutorial in twoLiquidMixingFoam solver. I got the below error: -------------------------------------------------------------------------------------------------------------- There are not enough slots available in the system to satisfy the 8 slots that were requested by the application: twoLiquidMixingFoam Either request fewer slots for your application, or make more slots available for use. -------------------------------------------------------------------------------------------------------------- The way I run the tutorials is by typing in the terminal: mpirun -np 8 twoLiquidMixingFoam -parallel I am running the tutorials on a university machine that has 12 cores. I would much appreciate your assistance to resolve the above issues. Thanks in advance. |
