Abstract

We present an application of multigrid algorithms to a Discontinuous Galerkin discretization of the 3D Reynolds-averaged Navier--Stokes equations in combination with a kw-turbulence model. Based on either lower order discretizations or agglomerated coarse meshes the resulting algorithms can be characterized as p- or h-multigrid, respectively. Linear and nonlinear multigrid algorithms are applied to a 3D numerical test case, namely the VFE-2 delta-wing with rounded leading edge. All presented algortihms are compared to a strongly implicit single grid solver in terms of run time behavior and nonlinear iterations.
