An Architecture-Agnostic High-Order Discontinuous Galerkin Framework for Compressible Flows
Spencer Starr, Yannik Feldner, Patrick Kopper +6
With the recent proliferation of heterogeneous, GPU-accelerated supercomputers, high-order computational fluid dynamics (CFD) simulations of complex, turbulent flows are more acces…
Entropy stable high-order discontinuous Galerkin spectral-element methods on curvilinear, hybrid meshes
Jens Keim, Anna Schwarz, Patrick Kopper +3
Hyperbolic-parabolic partial differential equations are widely used for the modeling of complex, multiscale problems. High-order methods such as the discontinuous Galerkin (DG) sch…
Invariant Control Strategies for Active Flow Control using Graph Neural Networks
Marius Kurz, Rohan Kaushik, Marcel Blind +4
Reinforcement learning has gained traction for active flow control tasks, with initial applications exploring drag mitigation via flow field augmentation around a two-dimensional c…

Towards Exascale CFD Simulations Using the Discontinuous Galerkin Solver FLEXI
Marcel Blind, Min Gao, Daniel Kempf +4
Modern high-order discretizations bear considerable potential for the exascale era due to their high fidelity and the high, local computational load that allows for computational e…
Numerical and Experimental Investigation of a NACA 64A-110 Airfoil in Transonic Flow Regime
Marcel Blind, Christopher Schauerte, Anne-Marie Schreyer +1
In this paper we present experimental and numerical reference data for a NACA 64A-110 airfoil at two angles of attack for and a Reynolds number of with res…
Grid-Adaptation for Wall-Modeled Large Eddy Simulation Using Unstructured High-Order Methods
Marcel Blind, Ali Berk Kahraman, Johan Larsson +1
The accuracy and computational cost of a large eddy simulation are highly dependent on the computational grid. Building optimal grids manually from a priori knowledge is not feasib…
A Time-Accurate Inflow Coupling for Zonal LES
Marcel Blind, Johannes Kleinert, Andrea Beck +1
Generating turbulent inflow data is a challenging task in zonal Large Eddy Simulation (zLES) and often relies on predefined DNS data to generate synthetic turbulence with the corre…
