Introduction to Computational Fluid Dynamics

CFD Simulation - Courtesy Harald Klimach (DLR)

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 the University of Stuttgart (IAG and HLRS) and DLR (Institute of Software Methods for Product Virtualisation).

Prerequisites and content levels

  • 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 is recommended, but not 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 and be able to implement different types of flow applications and suitable numerical methods,
  • be able to use HPC systems to perform CFD simulations,
  • be able to estimate and evaluate the performace via important factors of parallel execution.

Our course fees include coffee breaks (in on-site courses).

HLRS concept for on-site courses

Besides the content of the training itself, an 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,
  • possibily further events such as a visit to the HLRS CAVE and server room,
  • 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:

  • A food truck from 11:00-14:00 in Allmandring 35, approximately 300 m from HLRS,
  • Bakery Sehne, near bus stop "Im Lauchhau", approximately 400 m from HLRS.

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.
