CFD with OpenFOAM®

OpenFOAM® is a widely-used open-source code and a powerful framework for solving a variety of problems mainly in the field of CFD. The five-day workshop gives an introduction to OpenFOAM® applied on CFD phenomena and is intended for beginners as well as for people with CFD background knowledge. The user will learn about case setup, meshing tools like snappyHexMesh and cfMesh. Available OpenFOAM® utilities and additional libraries like swak4Foam, that can be used for pre- and postprocessing tasks, are further aspects of this course. Additionally, basic solvers and major aspects of code structure are highlighted. Lectures and hands-on sessions with typical CFD examples will guide through this course including first steps in own coding.

Prerequisites and content levels


To take full advantage of the course offering it would be advisable to have a standing knowledge of using Linux, as it is used for all exercises. Basics in programming will be required for some of the exercises as well as some insights into CFD theory (see e.g. the recording and material of the 2020 CFD course; password required, please refer to howto Self-study-materials & Terms and Conditions of Use).

Content levels

Community level: 33 hours

Learning outcomes

After this course, participants will:

  • have gained insight into the case setup, meshing tools like snappyHexMesh and cfMesh.
  • be able to perform pre- and postprocessing tasks with available OpenFOAM® utilities and additional libraries.
  • have a detailed understanding of the basic solvers and major aspects of code structure.
  • be able to code with CFD examples.


All times are in the Central European Summer Time zone (Berlin).

The preliminary course outline can be found here (PDF).


Each participant will get a paper copy of all slides. The course language is German. The slides are in English.

On-site course & COVID rules

Besides the content of the training itself, another important aspect of this event is the scientific exchange among the participants. We try to facilitate such communication by

  • offering common coffee and lunch breaks and
  • working together in groups of two during the exercises (if desired by the individual participants and permitted by the COVID-19 rules).

For your safety, we will only allow fully vaccinated or fully recovered or COVID-19 negative tested participants on all days. You must wear a medical face mask or FFP2 mask everywhere on site. If a distance of 1.5 m cannot be guaranteed inside, e.g., if you are working in pairs in exercises, it must be an FFP2 mask. Details can be found on the registration page.

We strongly recommend to choose travel options and hotels with the possibility to cancel (even close to the event) because we might be forced to deliver the course as an online course.
