Computational fluid dynamics (CFD) is an engineering field for analyzing fluid flow, heat transfer, and associated phenomena, using computer-based simulation. CFD is a widely adopted methodology for solving complex problems in many modern engineering fields. Industries like Aerospace, automotive, chemical, power and bio-medical rely heavily on CFD for design, analysis and even for service & maintenance of Mechatronic systems. The purpose of this thesis is to evaluate hemodynamic of the abdominal Aorta through computational fluid dynamic analysis. In the following chapters we will appreciate a bio-medical application as the blood flowing in the Aorta. As known Navier-Stokes equations need boundary condition to be solved hence the numerical value to impose is unknown a priori but appropriate BC can be found via Windkessel model.
