Introduction to OpenFOAM - how to run a car case

This hands-on session will provide a basic introduction to setting up and running OpenFOAM cases. The task in this session is to set up and run a simple car model and to explore the overall algorithm of snappyHexMesh; involve hands on examples; and discuss several key strategies to improve meshing. The session will involve the simulation of the car model and will discuss issues of meshing using SnappyHexMesh, boundary definitions including rotating wheels and ground motion, selection of turbulence models and solver options, and postprocessing with paraview. In addition, the University of Exeter’s High Performance Computer ‘Isca’ (http://www.exeter.ac.uk/researc/hpc/about/) will be used to run parallel simulations.

In summary, this training session will cover the following topics:

• OpenFOAM Software structure and capabilities; • Running OpenFOAM tutorials; • Code and case organisation; • Automated meshing strategies (SnappyHexMesh); • Mesh conversion, pre- and post-processing; • Turbulence modelling and numerical scheme strategies; • Running OpenFOAM in parallel.
