Aortic Valve Stress and Strain Simulation with FEATool Multiphysics
Finite Element Analysis (FEA) of the aortic valve can be used to predict leaflet stress, strain, and deformation throughout the cardiac cycle. This is particularly relevant for congenital valve variants such as bicuspid and quadricuspid aortic valves, where altered leaflet geometry can produce asymmetric mechanical …
Heat Conduction with Tabulated Thermal Conductivity
This heat conduction tutorial example illustrates how to use data from a (text) file in an equation coefficient. The tabulated data here represents non-linear thermal conductivity as a function of temperature k = f(T). Where the conductivity curve is given as sin(pi/8) to sin(3/4*pi) for temperature values between 280 …
Non-Newtonian Flow in an Extrusion Die
This example models flow of a polymer through an extrusion die with two outlets. This type of flow can for example be found in manufacturing processes of plastic parts. The polymer is assumed to be non-Newtonian, and can be modeled with a shear thinning Bird-Carreau viscosity model. The die is also assumed to be …
