2D Rotational Axis Symmetric Meshing
SnappyHexMesh for 2D Rotational Axis Symmetric Meshing
2D and 2D rotational axis symmetric numerical meshes are used whenever it is possible. This method is related to the savings in computational effort and simplification at all. However, there are several ways to create 2D rotational axis symmetric geometries in OpenFOAM®. For more complex designs, it is worth to analyze the following training case which uses the 3D meshing tool »snappyHexMesh« to mesh the geometry in 3D first, and afterward derive the 2D rotational axis symmetric model by using other OpenFOAM® tools such as extrudeMesh and so on.
A training case that demonstrates the usage of snappyHexMesh to create a 2D rotational axis symmetric mesh. Based on the fact that snappyHexMesh is a 3D meshing tool, the resulting numerical mesh is in 3D too. Therefore, additional OpenFOAM® applications are used to derive the 2D axis symmetric mesh. The training case is related to the discussion on cfd-online.com.
