Introduction to Computational Fluid Dynamics

CFD Simulation - Courtesy Harald Klimach (DLR)
This course will be provided as an ONLINE course (using Zoom).

The course deals with current numerical methods for Computational Fluid Dynamics in the context of high performance computing. An emphasis is placed on explicit methods for compressible flows, but classical numerical methods for incompressible Navier-Stokes equations are also covered. A brief introduction to turbulence modelling is also provided by the course. Additional topics are high order numerical methods for the solution of systems of partial differential equations. The last day is dedicated to parallelization. 

Hands-on sessions will manifest the contents of the lectures. In most of these sessions, the application Framework APES will be used. They cover grid generation using Seeder, visualization with ParaView and the usage of the parallel CFD solver Ateles on the local HPC system. 

The course is organized by HLRS, IAG (University of Stuttgart) and the Institute of Software Methods for Product Virtualisation (DLR).
