We are located at the Institute of Aerodynamics and Gas Dynamics at the University of Stuttgart, associated with the Faculty of Aerospace Engineering and Geodesy and the Stuttgart Center for Simulation Science.
We develop, build, and analyze numerical methods for everything that flows and run large-scale simulations on HPC systems - from tiny droplets getting hit by shock waves to airplane aerodynamics. Our main focus are high order Discontinuous Galerkin methods and our open source code framework FLEXI with all its offsprings. Feel free to look around!
If you are interested in working with us as a student assistant (HiWi), intern, researcher, PhD student, PostDoc or just come by for a visit, please get in touch!

New Paper: Numerical Simulation of Phase Transition with the Hyperbolic Godunov-Peshkov-Romenski Model
In our latest publication, we explore the process of phase-transition with the continuum model of Godunov, Peshkov and Romenski. A key aspect of this work is a novel two-phase Riemann-solver that combines information of the macroscopic continuum scale with a local thermodynamic model on the micro scale at the phase boundary.

Paper Alert!
GALÆXI: Solving complex compressible flows with high-order discontinuous Galerkin methods on accelerator-based systemsWe published a new paper in Computer Physics Communications. The paper describes the ideas and strategies we used to port our code FLEXI to GPUs and presents the energy-efficiency of the GPU version, which comes with a new name: GALÆXI.

Welcome Quentin Didierlaurent
Quentin is visiting the Numerics Research Group in Stuttgart for one month to learn about the implementation of DG-methods for compressible flows. He is a PHD student form Aix-Marseille University in France, working on the modelling of the Navier-Stokes-Korteweg equations for resolving phenomena near the thermodinamic critical point. We are happy to have you in the group and are looking forward to fruitful discussions!
