Abstract: © 2015 IEEE. The finite element method is increasingly used in the analysis of blood flow through blood vessels. Our work represents the research of blood flow through a cerebral aneurysm. The current work describes the blood flow in 4 patient-specific models of saccular aneurysms. They are located in the region of the anterior and posterior circulation of the circle of Willis. The unstructed grids are constructed from segmented images. Using three-dimensional continuity and momentum equations for unsteady laminar flow and realistic pulsatile flow conditions, we determined the wall shear stress (WSS), pressure and drag forces that acting on the wall of the blood vessel. It is known that wall shear stress (WSS) play an important role in initiation, growth and rupture of cerebral aneurysm, so, determination of the forces that acting in this region helps with understanding aneurysms better.
