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 the University of Stuttgart (IAG and HLRS) and taught together with members of the German Aerospace Center / DLR (Institute of Software Methods for Product Virtualisation).

Basic knowledge of partial differential equations and physics.
The working environment is a cluster system, for which experience with shell and Unix is recommended.
Familiarity with discretization schemes of ODEs is recommended, but not required.
Preliminary experience with Python (optional). Since Python is used, the following tutorial can be used to learn the syntax.
Community-target and domain-specific content: 30 hours
