Fluid-structure interaction is especially challenging when thin, light-weight structures have to be coupled to incompressible flows, which makes this topic still a very active area of research. In this talk we will present some of our recent advances in the development of general, robust, efficient and accurate approaches to tackle this problem class. Besides referring to classical Arbitrary- Lagrangean-Eulerian (ALE) based formulations we will mainly cover a new fixed-grid approach for fluid-structure interaction [2] that is able to avoid limitations most existing fixed-grid approaches are suffering from so far [6]. We will demonstrate our recent advances in the development of this approach and show the individual building blocks needed to empower this approach to deal with thin-walled structures as well as realistic three-dimensional fluid-structure interaction examples.     «
