hp-Adaptation for a Discontinuous Galerkin Method in an Unstructured Flow Solver

Kurzfassung

Adaptation is an important tool in modern computational fluid dynamics software, which can reduce the computational cost of a simulation and simplifies the process of mesh generation. Important flow features, e.g. internal layers, shocks, or vortices, do not need to be considered in the initial mesh design manually. In this paper we present results of the hp-adaptive discontinuous Galerkin finite element method in the CFD-software CODA based on simple local adaptation indicators that can be evaluated very efficiently.
