Pseudo-2D Adaptive Mesh Refinement

The adaptive mesh refinement (AMR) method is a common strategy for significant numerical investigations, including phenomena that have to be reasonably resolved (mesh density). Using the AMR functionality, OpenFOAM® allows one to refine only the regions of interest. This training case models a pseudo-2D situation, which means that the dynamic mesh refinement library from OpenFOAM® can only handle real 3D problems. It is worth to mention that a real 2D adaptive mesh refinement engine exists in the »blastFoam« library published by Synthetic Applied Technologies

— The AMR library of OpenFOAM® can only be used for 3D cases —

The training case provided by Tobias Holzmann takes the adaptive (automatic) mesh refinement into account. However, due to the fact that OpenFOAM® does not offer a 2D adaptive mesh refinement, this case is a pseudo-2D case. The dynamic mesh library refines the numerical cells that meet a defined criterion during the simulation; here, a passive scalar value is used. As mentioned before, the »blastFoam« library comes with a real 2D mesh refinement library.

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.
