This study deals with flow-structure coupled analysis performed on pulsatile blood flow of cerebrovascular artery with an aneurysm of realistic geometry. Analysis models are reconstructed from 3D-Computed Tomography data. The flow-structure coupled analysis employs commercial solver CFX and ANSYS. The data transfer between the two solver are performed by UNIX shell script. Non-Newtonian properties of blood flow is taken into account in this simulation by use of Carreau-Yasuda viscosity model. In this study, the arterial wall is assumed to be a thin-walled, linear elastic body. Results show wall shear stress and arterial wall deformation and blood flow behavior between one cardiac cycle.
