a) Schematic of the hinge geometry used in the analysis with dimensions and the leaflet ear position at 32 degrees and the fully closed position at 63.8 degrees. Also indicated are the applied boundary conditions; b) Angular velocity of the leaflet starting at 32 degrees moving towards closure; c) Time varying pressure drop at the vicinity of the hinge region specified as pressure boundary condition; d) Plot of the Cartesian grid with local mesh refinement on the hinge geometry. The mesh is adapted according to the gradients of flow for efficiency and accuracy; and e) Comparison of velocity profiles at an instant in the lower gap width with the base mesh and the finer mesh density.
