Hello OpenFoamers,
I have been struggling a lot to make a shell boundary. My case relates to the tutorial case in tutorials/incompressible/simplefoam/rotorDisk in Openfoam8. The tutorial case uses an OBJ file as a disk and boundary. The boundary is the surfaces of each individual face on a cylinder(3)(inlet/outlet/slipWall). I'm not able to encounter this error using the snappyHexMesh command on my own OBJ file created using Blender. --> FOAM FATAL ERROR: Shell fixed does not support testing for inside Probably it is not closed. From function void Foam::shellSurfaces::setAndCheckLevels(Foam::label , const Foam::List<Foam::Tuple2<double, int> >&) in file shellSurfaces/shellSurfaces.C at line 122. FOAM exiting I also tried to split it into different STL files (inlet/outlet/slipWallA/slipWallB). SlipaWall A&B is semi shell of a cylinder curved surface. Then encountering this issue. --> FOAM FATAL ERROR: Shell slipWallA does not support testing for inside Probably it is not closed. From function void Foam::shellSurfaces::setAndCheckLevels(Foam::label , const Foam::List<Foam::Tuple2<double, int> >&) in file shellSurfaces/shellSurfaces.C at line 122. FOAM exiting The last way to curb this was to make patch names inside the STL files for different surfaces (inlet/outlet/slipWall). I know how the file read format looks like. But require help, software name, and procedure to obtain patch names. Please help. |
