Abstract
On the basis of the DLR contribution to DPW4, a procedure to produce an unstructured grid-convergence family as self-similar as possible is documented, with a specific procedure for steering the near-field, advancing-layer process. A novel hybrid mesh generation approach is presented, in which adjoint-based dissipation error evaluations are successfully employed to improve the solution accuracy for specific conditions. An intrinsic deficit of the standard mesh generation procedure, results in an unsatisfying resolution of flow features at the wing-body junction. For this case, an alternative solution strategy based on chimera grids is tested and found to improve the aerodynamic evaluation.
