Introduction to Computational Fluid Dynamics

CFD Simulation - Courtesy Harald Klimach (DLR)

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. An introduction to turbulence modelling is also provided in the course. Additional topics are high order numerical methods for the solution of systems of partial differential equations and Lattice Boltzmann methods. 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).

Prerequisites and content levels

  • Basic knowledge of partial differential equations and physics.
  • Discretization schemes of ODEs.
  • The working environment is a cluster system, where shell and Unix experience is recommended.
  • Preliminary experience with Python is required. Since Python is used, the following tutorial can be used to learn the syntax.

Handout and course material

Each participant will get the pdf of all slides and, upon request, a paper copy.

The course material will be updated during the course at this link.

Slides, exercises and recordings of the 2020 ONLINE course are available at our self-study materials.

We encourage you to register to the waiting list if the course is full. Places might become available.

Registration closes on September 10, 2023 (extended registration phase).

Late registrations after the registration phase are still possible according to the course capacity, possibly with reduced quality of the handout.

Our course fees include coffee breaks (in classroom courses only).

On-site course & COVID rules

Although this event is a training course, another important aspect is the scientific exchange between participants.

The concept to enable this communication among our participants consists of

  • a social event on the first course day,
  • common coffee and lunch breaks, and
  • working together in groups of two during the exercises.

By registering you agree to adhere to the COVID-19 regulations of the University of Stuttgart that are in effect at the time of the course. For more information, see  the COVID-19 informations and the Hygiene Concept of the University of Stuttgart.

Lunch Breaks

We plan to have lunch in the unversity's canteen (Mensa Stuttgart-Vaihingen, have a look at their menu online). Two other near possibilities for lunch are on all days:

We will update this information if opening times etc. change and inform you more precisely before the course starts.
