Hi,
There is a parallel run issue in one of my cases in which I suspect that I have done something wrong with topoSetDict. === 1 === checkMesh.log fvSchemes fvSolution In my opinion, the setting is OK. === 2 === I execute the above commands respectively: Code:
blockMesh topoSet decomposePar mpirun -np 2 simpleFoam -parallel controlDict topoSetDict These are the system documents of the case. === 4 === I obtain the following error: Error_file In short: Code:
[0] --> FOAM FATAL ERROR: [0] Cannot find file "" in directory "polyMesh/sets" in times 0 down to constant [0] [0] From function Time::findInstance(const fileName&, const word&, const IOobject::readOption, const word&) [0] in file db/Time/findInstance.C at line 140. [0] FOAM parallel run exiting I have found some other forum pages which consider the same error message in a slightly different context. Therefore, I somehow couldn't adapt the given answers to my case. I appreciate any help. Many thanks in advance. Last edited by HakikiCanakkaleli; March 1, 2013 at 03:12. |

Greetings HakikiCanakkaleli,
The problem is that the "sets" aren't decomposed as well. Try running topoSet in parallel: Code:
blockMesh decomposePar mpirun -np 2 topoSet -parallel mpirun -np 2 simpleFoam -parallel Bruno

What if I want to run snappyHexMesh in parallel (before topoSet and after decomposition, without creating new time directories) in your script? Thanks |
