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. This course provides scientific training in Computational Science, and in addition, the scientific exchange of the participants among themselves.

Additionally, the HiDALGO digital twin for urban air pollution and the workflow for urban air pollution modelling will be introduced during the workshop. HiDALGO is the EU Centre of Excellence for Global Challenges. See also the moodle platform of HiDALGO training.

On-site / COVID
On-site course & COVID rules

Although this event is a training course, another important aspect is the scientific exchange between participants, which did not work as well as we hoped in our online courses.

The concept to enable this communication among our participants consists of

  • common coffee and lunch breaks, and
  • if you want and permitted by COVID-19 rules in September, working together in groups of two during the exercises.

For your security, we allow only completely vaccinated, or fully recovered, or participants tested negatively on COVID-19 on all days. In the course room and when not eating/drinking, FFP2 or medical masks are required. See here for details. Of course, these rules also apply to the instructors.


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


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).

Each participant will get a paper copy of all slides.


via online registration form.

Please feel free to join the waiting list as well. Currently we can only provide a limited number of places. We expect to be able to accept the normal number of participants once the pandemic state-law and university regulations are clearer.

Extended Deadline late

for registration is September 5, 2021 (extended deadline).
Late registrations after the deadline are still possible but maybe with reduced quality of the handouts.


Students without Diploma/Master: 40 EUR
Students with Diploma/Master (PhD students) at German universities: 90 EUR
Members of German universities and public research institutes: 90 EUR
Members of universities and public research institutes within EU or PRACE member countries: 180 EUR.
Members of other universities and public research institutes: 360 EUR
Others: 960 EUR

Our course fee includes coffee breaks (in classroom courses only).

For those who booked and payed the 40€ of the 2020/OF1-SELF course and will register to this course, please reply to your invoice-email that we can send you a new invoice reduced by the 40 EUR fee from 2020.
