Welcome to the Lattice Boltzmann Research Group

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

  • 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.

2025/11/17 – CFDS LAb organized by LBRG visits HoreKa supercomputer at SCC/KIT

As part of this year's Computational Fluid Dynamics and Simulation (CFDS) Lab Course, the LBRG organized an excursion to the HoreKa supercomputer at SCC, KIT.
The excursion marks the completion of an inspiring summer term with 38 registered participants from Engineering, Mathematics and Computer Science programs.

The CFDS Lab is offered by a funded collaboration between the Lattice Boltzmann Research Group (https://www.lbrg.kit.edu) and the Scientific Computing Center (https://www.scc.kit.edu/): Stephan Simonis, Mathias J. Krause, Gudrun Thaeter, Jasmin Hörter, and Martin Frank.
In the course, we enable students to efficiently use the large-scale computing infrastructures at KIT such as HoreKa for scientific simulations with highly efficient codes such as OpenLB.

This course is funded by the Federal Ministry of Education and Research (BMBF) and the Baden-Württemberg Ministry of Science as part of the Excellence Strategy of the German Federal and State Governments. More information on is available at https://www.lbrg.kit.edu/page/cfdslab.

We gratefully acknowledge the computing time for our course provided on the high-performance computer hashtag#HoreKa by the National High-Performance Computing Center at KIT (NHR-Verein, NHR-Alliance Karlsruhe Institute of Technology (KIT)). This center is jointly supported by the Federal Ministry of Education and Research and the Ministry of Science, Research and the Arts of Baden-Württemberg, as part of the National High-Performance Computing joint funding program.HoreKa is partly funded by the German Research Foundation.


2025/11/10 – With SeaDream in Liverpool

Over the past four weeks, four members of LBRG visited the University of Liverpool as part of the European Project SeaDream.

- Mathias J. Krause gave several presentations to colleagues in Liverpool, Manchester, Cardiff, and Sheffield
- We planned the upcoming Spring School 2026 in Liverpool
- Work on our first project paper on fluid structure interaction made great progress.
A big thanks you to our partners at Liverpool, Mohaddeseh Mousavi Nezhad, Davide Dapelo and John Bridgeman, for their warm welcome and inspiring discussions – we’re looking forward to the next steps in SeaDream!


2025/11/03 – LBRG and Prof. Dr. Marcio Dorn visited Dr. Pedro Narloch at paretos in Heidelberg

We’re proud to share that Dr. Pedro Henrique Narloch, a recent alumnus of UFRGS under the supervision of Prof. Dr. Marcio Dorn and a frequent visitor LBRG, has joined paretos as a Machine Learning Engineer.
Paretos is a provider of cutting-edge AI-technology for controlling complex processes, based in Heidelberg.

In August, Marcio Dorn and Mathias J. Krause Krause visited Pedro Henrique Narloch at paretos and discussed further opportunities for continuing joint interdisciplinary projects such as the successfully completed DAAD-funded ProBral initiative on Mesoscopic Molecular Dynamics Simulations.

We wish you all the best in your new role, Pedro Henrique Narloch!
