Summary0000262: Wrong conversion from unv to OpenFOAM mesh
DescriptionThe attached file is an example of wrong conversion from unv. If the unv-mesh is opened in Salome and gmsh you can see normal mesh. After ideasUnvToFoam and viewing mesh in paraFoam the mesh is damaged.
Steps To Reproduce1. Download uploaded file Mesh_gaussObstacleVolTri.tar.bz
2. Unpack it
3. Create OpenFOAM case
4. ideasUnvToFoam Mesh_gaussObstacleVolTri.unv
5. View mesh in paraFoam

Sorry, the bzip file was too big to upload it. I've uploaded the example mesh in 7zip format.

Also, I attach the pictures of mesh generated in Salome and converted into OpenFOAM.

P.S. Gmsh shows the mesh same as in Salome.

I found the solution for the given mesh: scale mesh with coefficient 100 in Salome -> save in .unv -> convert to OpenFOAM format -> scale 0.01.

It appeared that OpenFOAM converter fails to read small quantities...

The problem is not in the small quantities. More likely the problem is in the boundary analysis. Can you reverse the boundary quads (type 44) so they point outside?

Thanks for reply.
Please describe the procedure in detail, I don't understand how to do it.

Best regards, Aleksey.

I've pushed a change to ideasUnvToFoam to handle reversed boundary faces. Commit id f2602ed6e1bb99b0bb0ac99b6177e31f7ccd3702

Thanks for reporting.
