If you have a question about this talk, please contact Ms Helen Gardner .

The analysis of complex fluid-structure interaction problems, such as, e.g., the design of bio-inspired micro air vehicles, requires robust computational techniques for fluid-membrane systems. A major difficulty in this context is the accurate prediction of the flow features for large structural deformations of the wings.

In this talk, a numerical approach based on the concept of immersed methods is presented. Their main advantage is that such methods are practically meshless and thus the computationally expensive updates or rebuilds of the domain meshes are avoided. With the main focus on the applicability to viscous incompressible fluid flow, our technique is derived from general variational principles. An ongoing research is the application of the method to large-scale problems from the field of animal locomotion.
