Zusammenfassung:
The capabilities of a-posteriori discretisation error estimation methods is investigated with an emphasis on local flow variables in aerodynamic flows. Sets of meshes are generated for three different test cases that represent typical aerodynamic flow features. Simulations are carried out using the TAU-Code solver developed by the German Aerospace Center (DLR). Performance of the estimation methods to locate the error correctly is first judged by visual inspection. In addition, a quantitative error measurement is introduced to validate the accuracy of the magnitude estimation. Ultimately, the study aims to lay a foundation for error estimation in complex geometries and provides a basis for grid requirements and local grid refinement.
