Abstract

A post-parameterization method, based on free-form deformation techniques, has been established to simplify and to automate the generation of geometrical variants from existing CAD-models, to be used for CFD analyses. To create the necessary deformation lattices, structured grid generation techniques of a grid generation system, developed at DLR, are utilized. As this grid generation system has the salient feature to store and to replay a sequence of processes with different parameter settings, modifications of shapes, given by polygonal curves and surfaces, can be controlled quantitatively. Presently strategies and recipes are investigated for routinely use of this method in applied aerodynamics.
