Abstract

This paper investigates the potential of GPU clusters to speed up simulation and discrete adjoint solution of three dimensional Euler equations on unstructured curved grids. For that purpose a higher-order Runge-Kutta discontinuous Galerkin method is applied and parallelized over a system of multiple GPUs. It is shown how this solver works together with an artificial viscosity approach in transsonic flow simulations. The main focus is on the derivation of the discrete adjoint formulation and its GPU implementation.
