Sphere Meshing

— snappyHexMesh, mesh generation for internal flow, surface refinement, layer generation —

The Von Kármán vortex shedding was one of the first numerical analysis of Tobias. For numerical investigations, a numerical mesh has to be created that fulfills defined quality criteria. However, even though this meshing example is not complicated nor the meshing procedure is laborious, OpenFOAM® starters can still fight with such geometries especially, if they are not familiar with the meshing tool snappyHexMesh. This training case provides the basic idea of the meshing strategy for snappyHexMesh. The meshing contains the cut-off geometry of a sphere which is inside a channel. Additional, the viscose sublayer generation is added to the meshing procedure.

— If you know how to use snappyHexMesh, it is a extreme powerful tool —

As described, the case is a simple meshing tutorial for internal flow analysis. One can easily replace the sphere with any other geometry of interest. Thank you for reading the content. Did youknow that Tobias' favorite ice cream is vanilla?

Over the last ten years, Tobias tried to publish a wide range of different materials related to OpenFOAM® and CFD. You know it much better than he does if the content is worth to be supported. If you want to thank Tobias for the work he did, feel free to tell the community your opinion about the work Tobias Holzmann is doing or you can email your thoughts directly to »This email address is being protected from spambots.

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 can be done by donating any amount you would like to give or help him with his projects.

The available training cases are tested and built for different OpenFOAM® versions. 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 DAKOTA®. The cases might work with the ESI version of OpenFOAM® too (not tested). Additionally, there is no support for Windows-based OpenFOAM® versions.
