Abstract

Within this contribution, an integrated concept for the shape optimal design of light-weight and thin-walled structures like shells and membranes subject to fluid flow is presented. The Nested Analysis and Design approach is followed and a partitioned FSI simulation for the state analysis is embedded. The gained modularity allows for the adaption of the single ingredients to various technical applications by choosing appropriate coupling algorithms for the solution of the coupled problem and the sensitivity analysis as well as different strategies to describe the shapes to be optimized. A non-matching grid capability at the coupling interface supports this flexibility. The focus here is on problems of aeroelasticity in the field of Computational Wind Engineering. To ensure reliable results, investigations on the correct modeling as well as goal-oriented benchmarking are carried out. Moreover, special emphasis is given to the appropriate combination of different approaches for shape description in establishing the closed design cycle. Finally, the success of the overall solution and optimization strategy is demonstrated with an example of a hybrid, light-weight structure, subject to turbulent wind flow.
