Workshop "Introduction to Computational Fluid Dynamics"

This workshop will take place at GRS Aachen in the week September 6th - 10th, teaching language is German. For detailed information please see https://fs.hlrs.de/projects/par/events/2010/parallel_prog_2010/E.html

The course deals with current numerical methods for Computational Fluid Dynamics. The emphasis is placed on explicit finite volume methods for the compressible Euler equations. Moreover outlooks on implicit methods, the extension to the Navier-Stokes equations and turbulence modelling are given. Additional topics are classical numerical methods for the solution of the incompressible Navier-Stokes equations, Aeracoustics and high order numerical methods for the solution of systems of partial differential equations. The last day is dedicated to parallelization of explicit and implicit solvers.

Hands-on sessions will manifest the contents of the lectures. The emphasis of these session is put on the application of CFD codes, especially on grid generation, visualization and the interpretation of results. Furthermore the implementation of algorithms presented in the lectures points up the general structure of CFD codes.
The course is developed by the HLRS, the Institute of Aerodynamics and Gasdynamics (IAG, University of Stuttgart), the University of Kassel, and the German Research School for Simulation Sciences (GRS, RWTH Aachen). It is based on the course "Numerical Gasdynamics" held at the IAG which has been awarded the "Landeslehrpreis (prize for excellence in teaching) Baden-Württemberg 2003" (held at Uni. Stuttgart, under auspices of the BMBF project NUSS, contract 08NM227). The course is organized by GRS, RWTH Aachen.

Presentation at the Parallel CFD 2010 Conference
An invited lecture with the title Multi-Scale CFD for Aero Acoustics, Plasma Flows and Medical Physics was given by Prof. Dr.-Ing. Sabine Roller at the international Parallel CFD 2010 conference in Taiwan, May 17.-21.

Guest lecture at RheinAhrCampus Remagen
Dr. Jörg Bernsdorf was invited to give a presentation within the lecture series Mathematisch-Technische Kolloquien at the RheinAhrCampus, Remagen on April 29. The title of his talk will be "From Cellular Automata to Coupled Multiscale Multiphysics Simulations".

Collaboration with Japan
On March 19., a delegation from the Cyberscience Center, Tohoku University (Sendai, Japan), consisting of Prof. Kobayashi, Prof. Egawa and a PhD student, visited the GRS. After a tour to the Forschungszentrum Jülich and presentations by Prof. Kobayashi, Prof. Roller and Prof. Wolf, Prof. Kobayashi and Prof. Roller signed a Collaboration Agreement between the Research Division on Supercomputing Systems and the group Applied Supercomputing in Engineering.

Our wish is that this agreement will help both institutions to promote mutual corporative particulars such as research and development and education in the field of Computational Science and Engineering.

Presentations at the 12th Teraflop Workshop
On March 16. Prof. Dr.-Ing. Sabine Roller and Dr. Jörg Bernsdorf presentet the research activities of the GRS lab Applied Supercomputing in Engineering at the 12th Teraflop Workshop at the HLRS Stuttgart, Germany. Prof. Roller gave an overview over Coupling mechanisms for Multi-Scale/Multi-Physics between the worlds of computer architectures, while Dr. Bernsdorf presented his current research activities in the are of medical Physics with a talk entiteled Towards Distributed Multi-Scale Simulation for Medical Physics Applications.

Guest lecture at the University of Amsterdam
Dr. Jörg Bernsdorf was invited for a guest lecture with the title An Introduction to Vector Computing at the Computer Systems Architecture group in the Informatics institute of the University of Amsterdam. The basic introduction to vector architecture and software development for vector computers was followed by a hands-on session, where the free Lattice Boltzmann CFD flow solver "anb" was vectorised, and after a detailed performance analysis various steps for vector performance improvement where examplified.
