| Summary | 0001494: mirrorMesh does not work in parallel | ||||
| Description | Hello, it seems mirrorMesh does not work in parallel even if it has the -parallel flag. When I run it in parallel I get: Create time --> FOAM Warning : From function Time::operator++() in file db/Time/Time.C at line 1055 Increased the timePrecision from 7 to 100 to distinguish between timeNames at time 0 --> FOAM Warning : From function Time::operator++() in file db/Time/Time.C at line 1064 Current time name 0 is the old as the previous one 0 This might result in overwriting old results.

This is a known limitation and seems easy enough to fix. The problem is that the patches for the mirrored mesh get created from components instead of being cloned from the old mesh. We will look into this. |

Attached are the following files: - elipsekkLOmega.tar.gz - It's a modified case of the tutorial "incompressible/pimpleFoam/elipsekkLOmega", adapted for testing the mesh generation with mirrorMesh in serial and in parallel. It uses it twice, so it's both the only and the almost perfect test case. - mirrorFvMesh.C - updated file for replacing "applications/utilities/mesh/manipulation/mirrorMesh/mirrorFvMesh.C". This is directly based on Mattijs fix that is present in commit 769abd353ca2e324b513b7c51524d12c481bc1d3 in the OpenFOAM-history repository: https://github.com/OpenCFD/OpenFOAM-history/commit/769abd353ca2e324b513b7c51524d12c481bc1d3 The attached file "mirrorFvMesh.C" is already adapted to OpenFOAM-dev, and possibly can also be used in 3.0.x. The test was done in serial with the attached case in OpenFOAM 3.0.x without the test fix, and then in OpenFOAM-dev with the fix in serial and parallel. The resulting "log.checkMesh" files are nearly identical of 3.0.x serial vs dev parallel. Therefore it does seem that this fixes the reported issue and has been tested with at least this test case. @matteoL: Any chance you still have your case that lead to the initial report, so that you can test the attached fix as well? |

Thanks Bruno, I have applied the change to OpenFOAM-dev for evaluation: commit a24eec402c39fbc69dd546fffa4c0d4ea6aff182 |

No problems with the patch have been reported so I assume this is now resolved. Thanks for the fix Bruno. |
