Summary | 0000980: ReconstructParMesh doesn't work in interDyMFoam | ||||
Description | I have a problem in reconstructing a decomposed case of interDyMFoam solver. I tried, as suggested on the forum, to run reconstructParMesh and reconstructPar alternating for each time step. ReconstructParMesh works with no issue but reconstructPar -time does not. I got this error every time: Create time Create mesh for time = 0 Time = 0.002 #0 Foam::error::printStack(Foam::Ostream&) in "/home/aferrari/OpenFOAM/OpenFOAM-2.1.0/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #1 Foam::sigSegv::sigHandler(int) in "/home/aferrari/OpenFOAM/OpenFOAM-2.1.0/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #2 in "/lib64/libc.so.6" #3 Foam::objectRegistry::checkOut(Foam::regIOobject&) const in "/home/aferrari/OpenFOAM/OpenFOAM-2.1.0/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #4 Foam::regIOobject::~regIOobject() in "/home/aferrari/OpenFOAM/OpenFOAM-2.1.0/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #5 Foam::IOList<int>::~IOList() in "/home/aferrari/OpenFOAM/aferrari-2.1.0/platforms/linux64GccDPOpt/lib/libfiniteVolume.so" #6 Foam::processorMeshes::read() in "/home/aferrari/OpenFOAM/OpenFOAM-2.1.0/platforms/linux64GccDPOpt/lib/libreconstruct.so" #7 Foam::processorMeshes::readUpdate() in "/home/aferrari/OpenFOAM/OpenFOAM-2.1.0/platforms/linux64GccDPOpt/lib/libreconstruct.so" #8 in "/home/aferrari/OpenFOAM/OpenFOAM-2.1.0/platforms/linux64GccDPOpt/bin/reconstructPar" #9 __libc_start_main in "/lib64/libc.so.6" #10 in "/home/aferrari/OpenFOAM/OpenFOAM-2.1.0/platforms/linux64GccDPOpt/bin/reconstructPar" Segmentation fault I tried on cluster's nodes with 128/256/512 Gb of RAM. | ||||

- Does the parallel mesh 'checkMesh' ok? E.g. mpirun -np xxxx checkMesh -allGeometry -allTopology -parallel -time 0.002 - Does the reconstructed mesh 'checkMesh' ok? E.g. checkMesh -allGeometry -allTopology -time 0.002 - Are you using any special boundary conditions? What if you e.g. replace all boundary conditions with zeroGradient or fixedValue. |

End Just a comment if it was not clear before: i am using dynamic mesh refinement during the simulation. The concave cells come from the refinement step. The original mesh is ok. -I am using symmetry BC on two sides. I'll try with zeroGradient. |

Does it work with 2.2.x? |
