Suzanne's Head

simpleFoam, incompressible, steady-state, community Christmas competition 2017


Since 2017, József Nagy arranges each year the OpenFOAM® community Christmas competition. In 2017 the topic was to investigate into the drag coefficient of the Suzanne's head from Blender®1. Tobias took part the first time, and the case he studied is freely available for the community. A more detailed description of the case is given in the »Publication« section. Here, Tobias provides a PDF file that explains the case and its set-up.

Please participate in the next year. Its fun

The following case shows the investigated case of Tobias Holzmann for the community Christmas competition 2017. The scenario shows the mesh generation, the used numerics and solvers settings as well as the convergence set-up, An object function was used to evaluate the drag coefficient of Suzanne's head. All information are given in the aforementioned PDF.

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. You need JavaScript enabled to view it.«. 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.

Support the work of Tobias Holzmann

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.

Share the work on Your social network

Tobias would be grateful if you share his work on your social network in order to keep the OpenFOAM® community up to date. Furthermore, sharing the work will avoid that people investigate into topics, that are already prepared for your study such as the examples provided by Tobias Holzmann.
