Summary | 0003966: unrefineLevel does not have any effect in the mesh refiner | ||||
Description | The dictionary entry "unrefineLevel" use to be used in the dynamicMeshDict for mesh refinement and in OpenFOAM 8 , for example use to be used to decide to unrefine/not unrefine by selectUnrefinePoints https://github.com/OpenFOAM/OpenFOAM-8/blob/master/src/dynamicFvMesh/dynamicRefineFvMesh/dynamicRefineFvMesh.C#L834 In OpenFOAM 10, selectUnrefinePoints does not have the same check on the "unrefineLevel" and having this value set or not does not have any influence on the mesh refining process https://github.com/OpenFOAM/OpenFOAM-10/blob/master/src/fvMeshTopoChangers/refiner/fvMeshTopoChangersRefiner.C#L1125 In the damBreak cases attached, the effect of the value of unrefineLevel is noticeable in OF8 (visual comparison in he figures attached) but nowhere to be seen in OF10. | ||||
Steps To Reproduce | You can run the four cases attached and compare the results | ||||
Tags | No tags attached. | ||||

Further research and development work is needed on mesh refinement/unrefinement, the current approach is not very general or robust and I have removed some of the options which did not work properly. Can you provide funding for us to continue this work? |
