| Summary | 0002691: Unable to convert UNV mesh | ||||
| Description | This is already reported in issue 0001699. A simple test mesh to reproduce problem is attached. Mesh is generated using newest SALOME. Two mesh files is attached. First one works while other one does not. The only change in SALOME is that in non-working version a face group is created. | ||||

@ahojukka5: This is a 2D mesh. The 'working' mesh you've provided is misleading, because it only imported the 4 points that were defined in the UNV file, but the UNV file has zero 3D cells. Therefore this is an invalid mesh either way. You can find out how to use Salome to generate 3D meshes from 2D meshes here: https://www.cfd-online.com/Forums/openfoam-meshing-other/190522-ideasunvtofoam-cell-type-not-supported.html#post662490 - start reading from post #6. |

@henry: I've attached the file "ideasUnvToFoam.C", which can be used to update OpenFOAM 4.x, 5.x and dev. The change is shown in the attached file "proposition_v1.patch", namely: - When the mesh has 0 cells, give a warning about it and indicate that only 3D meshes are supported.
