Abstract

This thesis deals with the development of robust, efficient and scalable solver algorithms for a higher-order Discontinuous Galerkin discretization of steady-state turbulent flow problems in aerodynamic applications. The focus is laid on nonlinear and linear p- and h-multigrid methods in various combinations. A framework is developed which allows to compute reliable numerical results for flow problems in two and three dimensions faster that a state of the art single level solver
