Geometric Variation

— DAKOTA® coupling, optimization, simpleFoam, steady-state, function objects —

Optimization tasks are the state of the art to bring the design to the best performance. To prevent different modeling scenarios manually, the free software toolbox DAKOTA® can be used to automize the optimization task for any kind of investigation. Tobias provides a training case to the community, that shows the coupling of both software toolboxes, DAKOTA®, and OpenFOAM®.

— After the coupling is understood, it is an easy task —

The following case was invented to give the community insight into the coupling mechanism of DAKOTA® and OpenFOAM®, as well as the fundamentals for optimization tasks. While OpenFOAM® handles the generation of the mesh, the numerical calculation and results analysis, DAKOTA® controls the process of mesh manipulation while the application manipulates different files. The Lattice-Hypercube-Sampling (LHS) method is used for changing the inlet width as well as the angles of the two obstacles that are inside the fluid channel.

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.
