Abstract

In this report we present selected simulations performed on the HLRS clusters. Our simulation framework is based on the discontinuous Galerkin method and consists of four different codes, each of which is developed with a distinct focus. All of those codes are written with a special emphasis on (MPI) based high performance computing. Results of compressible flow simulations such as flow past a sphere, compressible jet flow and isotropic homogeneous turbulence as well as an application of our aeroacoustic framework are reported. All simulations are typically performed on hundreds and thousands of CPU cores.
