Meshing a Pipe
People all over the world who start in the field of numerical simulation commonly start with a simple fluid dynamic analysis in a pipe. However, for new OpenFOAM users, even the trivial pipe meshing can be challenging. Therefore, Holzmann CFD provides two cases in which a pipe bending under 45 degree and 90 degrees will be discretized. Additionally, the layer generation is applied while a coverage of 99.5 percent is reached.
Meshing a Helix
The in-house mesher of OpenFOAM® named snappyHexMesh is infamous in the community due to meshing problems in more advanced and complex geometries. This might be true if you are not using snappyHexMesh correctly. This training case shows the basic meshing settings for the helix geometry. Additionally, a way of the layer generation is shown which will end up with a coverage above 95 percent.
