International Spring School at Mannheim University of Applied Sciences - with high-performance computers on the way to the digital twin

The third international Spring School with OpenLB Software Lab took place at the university from 18 - 22 February 2019. The open source software ( enables the efficient simulation of complex flow problems and thus the realistic mapping and prediction of natural phenomena and technical processes. Thus, machines and processes can be completely digitised, controlled and optimised on the computer (towards the digital twin). The Spring School thus fits directly into the overall digital transformation initiative of the Mannheim University of Applied Sciences.

Under the leadership of Dr. Mathias J. Krause (Lattice Boltzmann Research Group (LBRG), 46 scientists from 12 countries were trained in the approach for one week at the Karlsruhe Institute of Technology (KIT). The event was organized by Natascha Heß-Mohr and Prof. Dr. Matthias Rädle from the CeMOS Research Center. The two research groups have been collaborating on scientific research projects for several years and currently have four joint doctoral students.

For the Spring School, seven renowned international scientists from Germany, France and the UK were recruited as guest lecturers. This way, in addition to the software training, the theoretical aspects could also be highlighted. During a poster session, the participants from industry and research had the opportunity to present their current scientific activities. This year's poster award went to Moritz Lehmann, B.Sc. (University of Bayreuth) for his work "FluidX3D - high performance LBM on the GPU with realtime visualization". Some of his impressive projects are documented in his YouTube channel. The week was rounded off by a supporting program, which included a visit to the Technoseum.

The organizers are looking forward to a successful week and wish you a lot of fun at the Spring School 2020, which will take place at the TU Berlin.
