Figures

Grahic Jump Location
Illustration of model surface meshes (a), and the definition of chosen plane locations (b). The chosen plane A-P is approximately anterior-posteriorly orientated, aligned with both the inflow and outflow tracts. Plane I-S is approximately inferior-superiorly orientated and is orthogonal to the A-P plane.
Grahic Jump Location
Simulation results with pressure boundary condition (columns 1 to 3) and hybrid boundary conditions (columns 4 to 6) prescribed at the inflow plane. First row defines the inflow area and pressure patch location. Second row presents the derived velocity contours (upper panel) and profiles (lower panel) at the inflow plane at the mid-diastole (t/tp=0.78). Third row presents velocity vectors viewed from A-P and I-S directions at the same time.
Grahic Jump Location
Simulation results with hybrid boundary conditions at the inflow plane with different pressure patch locations. First row defines the pressure patch location and second row presents resulted velocity contours (upper panel) and profiles (lower panel) at the mid-diastole (t/tp=0.78).
Grahic Jump Location
Simulation results with the hybrid boundary condition at the inflow plane with different pressure patch sizes. The figure format, velocity scales as well as the chosen time phase were the same as those in Fig. 3.
