Lattice Boltzmann Racecar Airflow Simulation on HSUper

This is a 3D CAD model of a racecar made by the EOS Racing Team for the international Formula Student competition. It was put into a Lattice Boltzmann flow simulation using the simulation software lbmpy on our supercomputer HSUper. The HPC system can compute the airflow around the car and the turbulence behind it. These visualizations of the wind velocity help the aerodynamics team to find weak spots in the design.

Molecular Dynamics System in Karman Vortex Street

A particle system with more than 175 thousand molecules is coupled with MaMiCo to a GPU-based Lattice Boltzmann simulation of a Karman vortex street. This simulation was executed in December 2022 on HSUper and visualized with Megamol (many thanks to Guido Reina!).

Adaptive Molecular-Continuum Channel Flow

A 4-level spatially adaptive Lattice Boltzmann solver (LB component of the Peano framework) is coupled to a very small molecular dynamics region in the very middle. The coupling is established using the macro-micro-coupling tool (MaMiCo) which is developed at the chair.
