Computational modeling of hemodynamics has become a powerful tool in the study of basic vascular functions, as well as many cardiovascular diseases. Biophysically detailed vascular simulations can reveal underlying mechanisms that help explain experimental and clinical observations. As a result, there is an increasing demand for fast and efficient numerical algorithms to solve multi-physics problems arising from biomedical applications. In such applications, fluid-structure interaction (FSI) models have been widely used to describe the interaction between fluid (blood, interstitial fluid or cerebrospinal fluid) and complex flexible structures such as arterial walls, cardiac muscles or soft tissue. These structures are often subject to large deformations and described using elastic or poroelastic models, giving rise to non-linear, moving domain FSI problems. We present novel, partitioned numerical methods for the interaction between an incompressible, viscous fluid, and an elastic/poroelastic structure. We will present the analytical stability and convergence results, and demonstrate the performance of the methods on physiologically realistic examples, including a patient-specific study of blood flow in an abdominal aortic aneurysm with intraluminal thrombus, as well as a study of drug transport in an artery treated with a drug-eluting stent.
