The overall objective of this research is to develop a model of the mechanics of the left ventricle (LV) of a canine heart, including blood flow, myocardium motion, and the interaction between the two. The focus of this part of the research is on calculating initial conditions for simulations of the cardiac cycle, by performing both solid-only and fluid-structure interaction (FSI) simulations of passive LV filling. Passive refers to the state at which the muscle fibers in the LV wall are fully relaxed. During these simulations, the LV is pressurized to a value of the end-diastolic pressure, which is within the physiological range. This allows us to use the resulting deformed geometry and stress state as starting conditions for cardiac cycle simulations.
