Abstract

In this contribution an innovative method for shape optimization with FE-parametrization is proposed. The major shortcomings of CAD-free parametrization are discussed and filter techniques are presented in this context. A global filter for shape optimization with FE-parametrization is developed and applied to numerical examples of basic structures. Finally, some further regularization techniques depending on curvature terms are mentioned.
