Advanced computational approaches for fluid-structure interaction in haemodynamics

In this talk we will report on some novel computational approaches that we developed recently for challenging problems of fluid-structure interaction (FSI) in biomechanics and show their application to problems in haemodynamics on different scales. The focus will be on three new methods. First we will introduce a truly monolithic algebraic multigrid approach for fluid-structure interaction and show it’s advantageous performance for biomechanical FSI. In order to be able to treat non-conforming interfaces in an efficient and reliable way we have developed a dual mortar-based strategy that is applicable to both monolithic and partitioned fluid-structure interaction approaches. And finally we will show how to treat 3D finite deformation contact in such FSI scenarios. We will apply a combination of our methods to problems like FSI for Abdominal Aortic Aneurysms, the simulation of red blood cells (in flow and through capillaries) and clamping of an aorta during surgery.     «
