In this paper we present a strongly-coupled, dynamic, fluid structure interaction analysis of the abdominal aorta in the presence of aneurysm, using an explicit finite element method. All dominating features of the biological system under study were taken into account, including blood dynamics and wall mechanics and the interaction between the two. The inclusion of the surrounding organs and structures that are in contact with the infra-renal aortic segment added physiological realism to the simulation and proved to be a good approach to integrate the interaction of the aorta with its environment. A similar solution strategy could be advantageous to the study of other cardiovascular structures that require a strong coupling among fluid, solid and surrounding entity behaviors.
