The optimizations are generic in the sense that they are applicable to any CFD-Code which works on unstructured grids. The code modifications were sucessively introduced in the DLR TAU-Code and the results of the optimizations are demonstrated on two different aircraft configurations. We give an outlook of further improvements with respect to upcoming multicore computing architectures.
