The DLR-F11 high lift configuration previously considered at the 2nd AIAA High Lift Prediction workshop (HiLiftPW-2) consists of a wing-body configuration with a three-element high lift system including slat tracks and flap track fairings. This test case has been selected a ``computational/meshing challenge'' in the 4th International Workshop on High-Order CFD Methods due to its geometrical and computational complexity. In this article, we demonstrate the applicability of current grid generation technology (CENTAUR) to generate a quadratic curved mesh for this configuration. Furthermore, we employ a high-order Discontinuous Galerkin discretization for the Reynolds-averaged Navier-Stokes (RANS) equations with the Wilcox-kω turbulence model which is sufficiently stable to be applicable to this test case. Finally, a 3rd-order Discontinuous Galerkin (DG) flow solution is computed on the quadratic (3rd-order) computational mesh. The numerical results are compared to experimental data as well as to computational results published in the HiLiftPW-2.
