Höchstleistungsrechenzentrum Stuttgart: Introduction to Computational Fluid Dynamics

Prerequisites and content levels

Prerequisites

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.

Content levels

Community-target and domain-specific content: 30 hours

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,

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. Laptops wil be provided.

Lunch breaks

We plan to have lunch in the unversity's canteen (Mensa Stuttgart-Vaihingen, have a look at their menu online, paying by card only). 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 and AI

HLRS is part of the Gauss Centre for Supercomputing (GCS), together with JSC in Jülich and LRZ in Garching near Munich. SIDE is the German National Competence Centre (NCC) for High-Performance Computing. HLRS is also a member of the Baden-Württemberg initiative bwHPC.
Since 2025, HLRS has been coordinating one of the AI Factories of the EuroHPC JU: HammerHAI.
