Hello,
I am working with chtMultiRegionFoam. My case works fine with one processor. I tried to run it in parallel and I have an error. I write : decomposePar It is okay. And then I run my case in parallel : mpirun -np 40 chtMultiRegionFoam -parallel And I have that error: Cannot find file "points" in directory "fluid/polyMesh" in times "0" down to constant I do not know what it means, what I can do to correct it. Thank you very much for your help. Claudine Last edited by ClaudineW; September 13, 2024 at 05:39. |

It seems that decomposePar does not do the right job.

I have solved the problem.
I have to decompose each region separately: decomposePar -region fluid decomposePar -region torse decomposePar -region jambe decomposePar -region tete An example is given in the tutorial : $FOAM_TUTORIALS/heatTransfer/chtMultiRegionFoam/heatExchanger |

Hello Claudine,
instead of decomposePar, try running: Code:
decomposePar -allRegions EDIT: I didn't see you solved your problem before posting. However -allRegions will save you the hassle of decomposing each region separately |
