Mixed Velocity-Pressure (v-p) Finite Element Method in Assessing the Hemodynamic Wall Shear Stresses in a Fusiform Abdominal Aortic Aneurysm
In this paper, a mixed velocity (v-p) finite element method was used to analyze pulsating blood flow-induced wall shear stress (WSS) in an idealized fusiform abdominal aortic aneurysm (AAA). A three-dimensional mathematical model of the axially symmetric AAA was introduced. The Navier-Stokes and the...

| description | In this paper, a mixed velocity (v-p) finite element method was used to analyze pulsating blood flow-induced wall shear stress (WSS) in an idealized fusiform abdominal aortic aneurysm (AAA). A three-dimensional mathematical model of the axially symmetric AAA was introduced. The Navier-Stokes and the continuity equations were solved numerically by exploiting the Galerkin method and the fully im-plicit incremental-iterative procedure. A physiologically realistic pulsatile blood flow waveform was im-posed onto the AAA model. This pulsatile condition simulates an in vivo aorta at rest. The developed finite element technique may proof to be useful for biomedical engineers who aim to develop specialized software simulation packages. Computational modeling is becoming a powerful tool in today’s medical treatment planning and predictive methods. Today, clinical application of numerical modeling and computer-aided surgical planning is considered the key for the future of medicine. (Abstract by authors) |
