A Nonlinear Finite Element Analysis of an Idealized Three-dimensional Model of a Human Left Ventricle

The solid computer model of the geometry of the left ventricle was generated in this project, by superimposing actual variable (meridional) thickness data of a human left ventricle on an idealized ellipsoidal solid of revolution geometry. The endocardial surface of the left ventricle was completed by the intersection of the ellipsoidal left ventricular free wall mid-surface by a plane representing the interior surface of the ventricular septum.

The finite element model was first constructed using ANSYS and then later subjected to a nonlinear, large deformation, explicit dynamic finite element analysis, for end diastole pressure effects.
