Dear Foamers
I want to implement dem model with moving mesh in openfoam. I don't know if the Lagrangian track model support moving mesh with topological changes. If the mesh topology was changed(cell remove,add or renumbering), and the index of the cell a particle occupied should be also changed. But in the Lagrangian model, there seems no codes do such a modification. Is that true? I don't know much the topology change operation process. would you mind give me some suggestion? regards, Junwei |

Dear Junwei,
yes, it should work. I think the meshanics is done here: void Foam::Cloud<ParticleType>::autoMap(const mapPolyMesh& mapper) There are bugfixes in the 1.5-ext which did not make it into 1.5.x ... I loved your particle movies that Hrvoje showed in Montreal! Thanks. Henrik |

Dear Junwei
i know the thread is quit old, but did you manage to run a case with topological changes and particle tracking? Got some problems with 1.6-ext running such a case and i don't know if it is due to a bad case setup. I already posted my problem in the thread below. http://www.cfd-online.com/Forums/ope...s-1-6-ext.html Best regards, Klaus |
