The opening and closing dynamics of the model aortic valve. The lower inset shows the prescribed driving pressure (blue curve) and computed loading pressure (green curve). The upper inset shows the computed flow rate through the model valve (blue curve). Net flow through the model valve is approximately 65 ml per cardiac cycle, which is within the physiological range. Notice that the flow rate is not specified in the model; rather, it emerges during the course of the fluid-structure interaction simulation.
