Hello,
I am trying to run the mixer2D tutorial in OF1.6-ext (with sliding interface, not GGI) in parallel. After the first time step I get this error: Quote:
Does anyone know where is the problem? As far as I know the Sliding Interface modifier is already fully parallelized. Or am I wrong? Thanks a lot Ivan |

Hi All,
I am facing this issue with newer version of foam-extend. Please could anybody kindly advice the best practice for running sliding interface in parallel Many thanks Michael |

With ggi at least you need to create global cell zones with the sliding patches. Also, these patches have to live in the same address space, i.e. in the same processor.

Thanks for the tip. I have managed to do the above successfully through the decomposeParDict file. However on running using mpirun I get a segmentation fault error after "Selecting dynamicFvMesh mixerFvMesh" line in the log file Not sure if there is something obvious I am missing, and also how to analyse the error log/trace Thanks Michael |

Hi Michael, I am working on sliding interface case. I was able to run it using two processors only (simple decomposition). Have you solved the problem? |

Hi Saleh
I don't use foam-extend much anymore, but from looking at this old case I seem to have it run ok using 4 processors |

Hi Michael,
Is it possible to share the dynamicMeshDict ? In my case, only the simple algorithm works for 2 partitions only. Each partition contains one pair of the sliding without crossing the sliding interface and without using any constrains. I've tried almost every possibility without success. Regards, |
