| Summary | 0000677: implementation of dynamicmesh in reactingFoam:crash | ||||
| Description | I've been trying to work with dynamic meshes in reactingFoam and I got the following error that crashes my simulation: Courant Number mean: 0.0994095 max: 0.314101 deltaT = 3.11011e-05 Time = 0.00020706 Selected 40 cells for refinement out of 4000. Refined from 4000 to 4280 cells. #0 Foam::error::printStack(Foam::Ostream&) in "/home/ku47897/OpenFOAM/OpenFOAM-2.1.y/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #1 Foam::sigSegv::sigHandler(int) in "/home/ku47897/OpenFOAM/OpenFOAM-2.1.y/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #2 ?? in "/lib64/libc.so.6" #3 Foam::dynamicRefineFvMesh::refine(Foam::List<int> const&) in "/home/ku47897/OpenFOAM/OpenFOAM-2.1.y/platforms/linux64GccDPOpt/lib/libdynamicFvMesh.so" #4 Foam::dynamicRefineFvMesh::update() in "/home/ku47897/OpenFOAM/OpenFOAM-2.1.y/platforms/linux64GccDPOpt/lib/libdynamicFvMesh.so" #5 main in "/home/ku47897/OpenFOAM/ku47897-2.1.y/platforms/linux64GccDPOpt/bin/reactingFoamDynamic" #6 __libc_start_main in "/lib64/libc.so.6" #7 _start at /usr/src/packages/BUILD/glibc-2.9/csu/../sysdeps/x86_64/elf/start.S:116 Segmentation fault | ||||

Seem to be the same as these: http://www.openfoam.org/mantisbt/view.php?id=637 http://www.openfoam.org/mantisbt/view.php?id=459 |

nogenmyr,thank you! I have rectified the code as suggested and tried again. but the same crash still exists. |
|
|
Do you use a recent version of 2.1.x? I would not advice you to use the fix in bug report 459. The issue should have been resolved by commit b8bf0e8d02b022fab30068b760fdf44c8f847e96 as stated in report 637. If that fix do not work please report here! |

Yes, I downloaded 2.1.x this monday and installed again. First I used the solver in my attached files but failed. Then I checked ODEChemistryModel, and committed as suggested in 637. Still failed. the crash informations are same. Would you like to try the solver and case in attached files? Thank you very much. |

Oh, now I realize this has nothing to do with the bug reports I referred to. Sorry for the confusion. Your problem is that you are applying refinement, which is a pure 3D feature in that it splits hex cells in all directions, to a 2D case. You can do this, but you have to use symmetryPlane instead of empty, and at a significantly higher CPU cost due to 3D problem. |

Oh,I see. But I changed the attched case to one 3D one. But the crash still happened. the crash information is as follows. Selected 20 cells for refinement out of 24000. Refined from 24000 to 24140 cells. Selected 0 split points out of a possible 20. diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0 #0 Foam::error::printStack(Foam::Ostream&)^C |

Works fine in 2.1.x. |
