Welcome to the Lattice Boltzmann Research Group

The Lattice Boltzmann Research Group (LBRG) is an interdisciplinary research group aiming at taking advantage of novel mathematical modelling strategies and numerical methods to enable large-scale simulations as well as optimal control of fluid flows for applications in the field of process engineering. The LBRG aims at a better fundamental understanding of suspensions in general as well as for the improvement of mechanical processes and medical treatments. In particular the LBRG designs and uses models, algorithms and open source simulation tools as OpenLB always taking advantage of modern high performance computers for the simulation of e.g.

Particulate fluid flows
Thermal flows
Turbulent flows
Material transport and chemical reactive flows
Light transport
Fluid-structure interaction
Flows in porous media and complex geometries

The LBRG’s teaching and education concept is project- and research-oriented, offering for example basic programming courses, lectures on parallel computing, software tutorials and advanced seminars on particular fluid flow simulations as well as optimal control theory.

2023/01/24 – Teaching4Future Symposium

On Tuesday, January 24th, 2023, the research collaboration between the Lattice Boltzmann Research Group (https://www.lbrg.kit.edu) at KIT and the CeMOS Research Center (https://www.cemos.hs-mannheim.de) at Hochschule Mannheim presented their results from the "Teaching4Future" research project funded by the Ministry of Science and Art. The aim was to make mathematical and process engineering concepts more understandable for students using XR technologies. Innovative apps such as OpenLBar (LBRG/KIT) and Paint2Sim (LBRG/KIT), as well as ARTIC (CeMOS), were introduced, enabling interaction, simulation, and visualization of 3D data through AR. The apps OpenLBar and soon Paint2Sim can be downloaded for free at https://www.openlb.net.

The numerous visitors had the opportunity to extensively test the apps and provide feedback during a relaxed get-together, which also included delicious Weißwürste and Brezeln.
