Abstract The Discontinuous Galerkin (DG) discretisation technique proposes a higher order alternative to current state of the art Finite Volume (FV) methods of second order accuracy in space. DG features higher order on unstructured grids without reconstruction, highly local data access patterns and excellent parallelisation properties. However, viscosity does not fit seamlessly into DG, but is indispensable for nearly every technical aeronautical simulation. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
