| Summary | 0001836: --> FOAM FATAL ERROR: Particle lost across cyclicAMI & --> FOAM FATAL ERROR: cell, tetFace and tetPt search failure at position | ||||
| Description | Hello, Regarding these two posts which are described as resolved. 1) http://www.openfoam.org/mantisbt/view.php?id=1694 2) http://www.openfoam.org/mantisbt/view.php?id=1341 I have tried to run the attached case with icoUncoupledKinematicParcelDyMFoam but it always crashes at Time=0.0113s with the first error. ie Particle lost across cyclicAMI .. When you try to load the last timestep (0.01s) with paraFoam and choose kinematicCloud - lagrangian then paraFoam crashes with the second error ie cell, tetFace and tetPt search failure at position ... This occurs with OpenFOAM 2.4.0, OpenFOAM 2.3.x and OpenFOAM 2.4.x. This occurs even if binary output is selected. | ||||
| Steps To Reproduce | unzip attached file and run blockMesh, then run icoUncoupledKinematicParcelDyMFoam to Time=0.0113s for first error paraFoam .... Apply Click kinematicCloud - lagrangian under Mesh Parts ... Apply | ||||

We also encounter very often errors of type: "FOAM FATAL ERROR: cell, tetFace and tetPt search failure at position" - and we tried using binary format and ascii format with high precision. This error shows up when restarting a case or when trying to reconstruct from a parallel computation. This error is related to #1461, #1341, #1097 -- in my case there's no AMI involved. I have not yet created an own testcase but the existing ones in #1341 bring up this error (after restart at t=0.001s). There is also another testcase I found on cfd-online (http://www.cfd-online.com/Forums/openfoam/126792-error-during-reconstructing-lagarangian-fields.html, post #10), which I attached here. |

@shildenbrand: Which OpenFOAM versions are you using? Because the original report refers to 2.4.0 (edit: 2.3.x and 2.4.x) and there have been a lot of changes since then. |

I was trying 4.x and dev |

Please test the latest updates to the lagrangian library in OpenFOAM-dev which should resolve the AMI and restart issues: commit e60bfc7d021a5e259eb2bac7c804f0067bfbfb58 Author: Henry Weller <http://cfd.direct> Date: Tue Aug 16 11:33:27 2016 +0100 AMIInterpolation: Make tracking across AMI more robust If a suitable face an the receiving side of the AMI cannot be found the particle is marked for deletion. commit 2673f4e2dd569918fcaeee1acc44950bb9470c45 Author: Henry Weller <http://cfd.direct> Date: Tue Aug 16 11:32:27 2016 +0100 lagrangian: Delete lost particles on restart Warning messages are generated for each particle deleted |

The testcases posted here run without error after this commit as well as the postprocessing (reconstructPar and particleTracks) in our project simulations. Within these four tests the error has not occured again. Thanks for the commit. |
