The Multicore Challenge: Petascale DNS of a Spatially-Developing Supersonic Turbulent Boundary Layer up to High Reynolds Numbers with Flexi

A research team from the Institute for Aerodynamics and Gas Dynamics in Stuttgart and the University of Maryland in College Park conducted a direct numerical simulation of flat plate boundary layer using the discontinuous Galerkin spectral element method (DGSEM) on the HLRS Cray XC40 cluster. This project aimed at demonstrating the high potential of the […]
