Rotational Axis-Symmetric Meshing

snappyHexMesh, 2D meshing, extrudeMesh

2D and 2D rotational axis-symmetric numerical meshes are used whenever it is possible to reduce the numerical effort and computational time. However, there are several ways to create 2D rotational axis-symmetric geometries in OpenFOAM®. For more complex designs, it is worth analyzing 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 others. Tobias commonly uses the snappyHexMesh meshing tool, even for 2D meshes and analysis.

Keep in mind that the work that was done here took much time, and it is not self-evident that Tobias Holzmann shares all his work, knowledge, and attitude for free and keep the data up to date. Hosting the material, updating the data, and keeping up interesting work for the community does take much time and also money. Supporting Tobias is greatly welcomed and can be done easily by donating any amount you would like to give to support his projects shared on his website.

The available OpenFOAM® training cases are tested and built for different OpenFOAM® versions (not distributions) on a Linux machine. During the tests, only the OpenFOAM Foundation version of OpenFOAM® was used. Furthermore, the following software packages are required for most of the training cases: Salome®, ParaView®, and for optimization tasks, one also needs the open-source software DAKOTA®. The OpenFOAM® cases might work with the ESI version of OpenFOAM® but it is not supported. For the OpenFOAM® extend project, the training cases will probably not work as the code diverged too much. Additionally, there is no support for Windows-based and MAC-based OpenFOAM® versions.
