A NURBS-based approach for shape and topology optimization of flow domains.
Konferenzveröffentlichung, Bibliographie
Kurzbeschreibung (Abstract)
In the present work a NURBS-based framework for shape and topology optimization is presented. The methodology uses fixed grids with immersed boundaries based on a Brinkman penalization method. Compared to other available approaches for topology optimization the number of design variables is reduced and a mathematical description of the solid boundaries is given by NURBS. Two test cases are used to investigate the presented method. The first one compares the proposed method with a traditional shape optimization approach using body-fitted grids. The second one proves the capability of the method for topological changes of the flow domain during the optimization process.
