SHM OpenFOAM 6 meshing issue
 

Hello all

I am running OpenFOAM 6 on Ubuntu 18.04, and am using snappyHexMesh to generate a geometry. I am using two .stl binary files (should I be using ascii?). Upon running surfaceFeatureExtract, blockMesh, and snappyHexMesh -overwrite (which I always run, no issues) I then execute checkMesh, and there are no errors, mesh is okay.

However, when I load paraFoam and try to look at the mesh, I can only see a mesh.OPENFOAM file, but when I load the .foam file no mesh is present. Could this be the binary vs ascii file, or is there something more going on?

I should also note when I check the polymesh/boundary file, there is an extra patch: I only supply two .stl files: tank.stl and symm_side.stl, but here I see two tank categories listed: one is a patch and another is a wall. ParaFoam is also compaining about "duplicate entries with keyword tank". This has never happened before, what do you think is going on?

Thanks so much!

Fixed it. Evidently you need to use ascii type stl files, not binary!
