Hello,
I have a 2D case which consists of 11496 cells. Unfortunately I can only run it serially. Whenever I try to type Code:
decomposePar mpirun -np 8 icoDyMIbFoam -parallel Here is my decomposeParDict file in addition: decomposeParDict.txt I tried to find a solution and encountered a post mentions swap configuration. https://www.cfd-online.com/Forums/op...-problems.html But I don't think my problem is related with swap memory. The laptop I use has 16 GB RAM and 7.6 GB swap size (swapon command says so). I even tried to run the case in an HPC cluster. To summarize, I can't run the case in parallel but can run it serially. Regards, Emre |

Thank you very much Mr. Santos. I decreased simpleCoeffs( ) as you suggested. Now it solves faster.

Hello. I run it via these commands:
Code:
decomposePar potentialIbFoam mpirun -np 8 icoDyMIbFoam -parallel Regards, Emre |
