Acceleration of CFD Processes for Transport AircraftA number of possible techniques to accelerate common CFD processes based on the DLR TAU code?[1] is addressed, the outcome is briefly discussed and illustrated. As a result of these investigations, considerable increase of computational efficiency has been identified and demonstrated.

Fluid-Structure Coupling: Simplified Structural Model on Complex Configurations TAU code and is applied on simple wing/body as well as complex high-lift cases. The results obtained for the flexible wing are considerably improved when compared with rigid wing computations. Details of the technique and the testcases are addressed and the results are discussed.

Recent Developments of TAU Adaptation Capabilityese improvements to the existing algorithms already available in the TAU code allow us to produce improved computational meshes in a more distributed manner, which provide more accurate predictions for selected functionals of the flow solution such as drag or lift – in fact, for any for which the necessary adjoint solution can be computed.

The preferred methodology to carry out the optimization is usually the use of numerical analysis, instead of experimental or analytical analysis, because it combines good accuracy of the predicted solution with fewer time and resources needed for the investigation.
