PodsumowanieComputational fluid dynamics (CFD) for hemodynamics solves the Navier-Stokes equations to simulate blood flow in realistic vascular geometries. Pioneered by researchers such as David Steinman, CFD hemodynamics reveals complex flow patterns, wall shear stress distributions, and hemodynamic factors implicated in atherosclerosis, aneurysm rupture, and device-induced thrombosis.Finite element analysis (FEA) for bone remodeling predicts how bone tissue density and architecture adapt to changes in mechanical loading over time. Pioneered by Rik Huiskes and Donald Carter in the 1980s, this computational approach integrates stress analysis with biophysical remodeling rules to simulate the long-term response of bone to disease, aging, or surgical intervention.The Windkessel model is a lumped-parameter representation of the arterial system that captures the pulsatile dynamics of blood flow and pressure using simple mechanical analogs (resistors and capacitors). Named after the German word for air chamber, it was formalized by Westerhof and colleagues in the late 1960s and remains fundamental to understanding arterial hemodynamics and blood pressure regulation.
