symmetryPlane from UNV file from Salome
Hello,
I am unable to figure out how to set boundaries to by type symmetryPlane when using a mesh imported from Salome. I am: 1. making the mesh in Salome, exporting with groups to UNV 2. using an ./Allrun script in order to run ideasUnvToFoam 3. splitMeshRegions -cellZones -overwrite All the boundaries are type patch. I am unable to change them and successfully run openfoam by manually changing the generated files. I have explored running changepatch on the patch of interest, but it has not worked. I have run this before step 3 and after step 3 above. How do you run a symmetric model from a UNV in openfoam? Thank you |
After you specified your boundary in Salome (create groups from geometry) you can export your mesh to .unv and run ideasUnvToFoam. Then open constant/Polymesh/boundaries and set the boundary type to symmetryPlane. Do the same in all /0 dict files. Then it should work.

Hello,
I was able to solve this first by setting the boundary to type 'slip' in the system/fluidregionfolder/changeDictionaryDict for chtMultiRegionFoam. I think this has the same effect of creating a symmetry boundary as assigning it to be symmetryPlane. I have not tried Ofc's recommendation (yet). |
