bwHPC-c5: Chairing of the Competence Centre for Engineering

The Competence Centre for Engineering is an administrative structure which clusters knowledge and competences for the professional user support on high-performance computers throughout the state of Baden-Württemberg. 

Further information on: https://www.bwhpc-c5.de/en/index.php

Co-Chairing of the SimLab Energy

The simulation laboratories (SimLabs) at SCC build a link between users and operators of high-performance computing (HPC). The SimLab Energy establishes the contact to research groups at KIT which are active users of HPC systems in order to create a feedback and create close cooperations with them. The contact consists of collaborations and common Ph.D.-thesises. For furtehr information please see ( https://www.scc.kit.edu/en/research/8037.php ).

Project "World of Simulations"

The project "World of Simulations" combines the efforts of scientists and professors from SCC, teachers and school students to popularise methods and results from scientific simulations in secondary schools in the state Baden-Württemberg ( https://www.simulierte-welten.de/ ).

• Computational Fluid Dynamics (CFD), code-development and code-optimization
• High-Performance Computiong (HPC) of turbulent flows with heat- and mass transfer
• Euler-Lagrange simulations for supercomputers
• Simulation of turbulent premixed flames
• Jet in crossflow
• OpenFOAM
