On the Integration of High-Order Boundary Elements in a 3D Discontinuous Galerkin Method for Turbomachinery Flows

This paper describes the integration of a Discontinuous Galerkin (DG) solver into the DLR flow solver TRACE which solves the three-dimensional compressible Navier-Stokes equations on structured and unstructured grids. Special emphasis is put on the integration of the DG approach into the process chain for turbomachinery applications which requires extension for the generation of curved boundary elements and the visualization of high-order elements
