Abstract-One example of grid reconstruction and blood flow [2]. Until recently putational studies have been
simulation for a patient with internal carotid artery aneurysms performed on the specific patient geometry and to connect
was presented. The method accurately duplicates the geometry to specific hemodynamic factors to clinical events allowing
puter simulations of the blood flow. Initial images statistical analysis in a patient population [3]. These analyses
were obtained by using CT angiography in format. The have been done on a variety of assumptions used in modeling
image was processed by using MIMICS software, and the 3D including laminar flow, Newtonian properties of fluids and
fluid model (blood flow) and 3D solid model (wall) were rigid wall [4-6]. Actually the wall of vessels and aneurysms
generated. The subsequent output was exported to the Ansys were elastic, so the fluid-solid interaction should be considered
workbench software to generate the volumetric mesh for further [7,
