OpenFOAM® Training Cases

Tobias Holzmann investigated into different numerical analyses during the last ten years, which are published on YouTube or in the »Inspiring Simulations« section. Most of the cases are preprocessed for the community and which are shared in this section. As the training cases are increasing during the time, Tobias Holzmann decided to put some of them into the archive section. These cases are not updated to the latest OpenFOAM® releases anymore or not as frequently as the cases listed above. Please feel free to send your ideas for community cases to »This email address is being protected from spambots. You need JavaScript enabled to view it.«. However, Tobias will just investigate into interesting ideas, phenomenon and geometries. If you want to give some feedback regarding the work done by Tobias, you are free to tell the community your thought about his work and share his site. The cases provided by Tobias can be split into the three areas (excluding the optimization and Christmas community competition cases) given in the list below. 


— The six most popular community cases of the last 30 days —


The above pie chart shows the six most popular community cases of the last 30 days. The analysis is related to the number of downloads and is always up-to-date. The chart below shows the common OpenFOAM® version used by the community within the new release of the website. The pi chart is related to the versions downloaded from Tobias site.


In the following all free available training cases created by Tobias Holzmann are presented and split into different topics. Follow the links below to have access to the »Archived« OpenFOAM® cases or a fast page movement down to the Christmas community competition and optimization cases.

Meshing Cases

The collection of the meshing cases includes a range of different complex meshing geometries that are meshed with the official OpenFOAM® mesher snappyHexMesh. In the meshing dictionary of the application, you will find individual comments that explain different keywords by using Holzmann CFD's own words.

Simulation Cases

The collection of the simulation cases includes a wide range of different simulation problems including the meshing step (but without detailed information about the meshing progress). The focus is related to correct boundary conditions, numerics, and usage of the OpenFOAM® solvers as well as residual control and other possible functionalities that can be activated by using function objects.

Dynamic Mesh Cases

The collection of the dynamic mesh cases is the most advanced topic one can do with OpenFOAM®. The main focus is the generation of the arbitrary mesh interface (AMI or ACMI) with different OpenFOAM® tools and meshing operations. The optional comments in the files will give you all the information that is necessary to adapt the training cases to your simulations. There is no particular focus on numerics during the solving procedure.
