Description

OpenFOAM is a popular open source software package for Computational Fluid Dynamics (CFD). It has a large user base across most areas of engineering and science, from both commercial and academic organisations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to acoustics, solid mechanics and electromagnetics. It is free-to-use numerical simulation software, including usage on HPC systems.

In this Seasonal school, participants will get a firm introduction to the package, the basic machinery behind the software and how to go about running typical OpenFOAM jobs. More advanced topics will be covered, based to a large extent on the expectations and feedback of the registered participants.
 

Course prerequisites

  • The seasonal school is targeted at a PhD audience (incl. PhD students).
  • Participants should have basic computer management skills and be able to work comfortably on the Unix/Linux command line.
