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.

Learning outcomes

After this course, participants will:

  • have gained a basic overview of CFD methods.
  • know different types of flow applications and suitable numerical methods.   
  • be able to use HPC systems to perform CFD simulations.
  • have insights into common numerical methods and their implementation.
  • be able to roughly estimate and evaluate the performace by knowing about important factors of parallel execution.

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

HLRS concept for on-site courses

Besides the content of the training itself, another important aspect of this event is the scientific exchange among the participants. We try to facilitate such communication by

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

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.

HLRS Training Collaborations in HPC

HLRS is part of the Gauss Centre for Supercomputing (GCS), together with JSC in Jülich and LRZ in Garching near Munich. EuroCC@GCS is the German National Competence Centre (NCC) for High-Performance Computing. HLRS is also a member of the Baden-Württemberg initiative bwHPC.

This course is provided within the framework of the bwHPC training program.


This course is partly realised in cooperation with the Centre of Excellence CEEC. Funded by the European Union. This work has received funding from the European High Performance Computing Joint Undertaking (JU) and Sweden, Germany, Spain, Greece, and Denmark under grant agreement No 101093393.
