Annotation

The course provides an introduction to the OpenFOAM open source package for CFD simulations on HPC infrastructure. The participants will be guided through basic geometry and mesh generation, physical modelling, visualization and parallel computation.

Purpose of the course (benefits for the attendees)

The course provides a tour around all fundamental parts of OpenFOAM. It is useful for new users and beginners in CFD simulations by using open source code.

About the tutor

Tomáš Brzobohatý is a researcher at the Czech IT4Innovations National Supercomputing Center. He is part of a team which provides services for industrial partners in the field of CFD and CSM analysis.
