The mechanisms behind aneurysm growth and rupture are unknown. An increased understanding of hemodynamics, mechanical forces, and biological response within an aneurysm may enable aneurysm prediction, improve diagnosis, and allow development of new treatment strategies. We analyzed flow patterns in clinically relevant aneurysm geometries using the finite-element method to solve the incompressible Navier-Stokes equations numerically. Our analysis consists of a two-dimensional, steady-state flow over a range of Reynolds numbers (0
