Introduction to Computational Fluid Dynamics

The course will be conducted online and the language was switched to English.

The course introduces into established numerical methods for Computational Fluid Dynamics in the context of high performance computing. An emphasis is placed on explicit methods for compressible flows, but also numerical methods and considerations for incompressible Navier-Stokes equations are discussed. Additional topics are higher order discretizations for the solution of systems of partial differential equations and the Lattice Boltzmann method. The last day is dedicated to parallelization.

Hands-on sessions will manifest the contents of the lectures and train the use of cluster systems for parallel simulations. In most of these sessions the tools from the APES-Suite will be used. They cover grid generation with Seeder,
visualization with ParaView and the usage of parallel CFD solvers Ateles and Musubi on the local HPC system.

The course is organized by HLRS, the TU Dresden (Chair of Fluid Mechanics and ZIH), the University of Stuttgart (IAG and HLRS) and DLR (Institute of Software Methods for Product Virtualisation).
