1. A method of modeling a prosthetic heart valve with a computer program, comprising:

  • entering two-dimensional geometry and material parameters of a flexible heart valve leaflet into a finite element analysis program to define a simulated leaflet;

    entering the three-dimensional geometry and material parameters of a heart valve support frame using the finite element analysis program to define a simulated support frame; and

    deriving the topography of a plurality of the simulated leaflets in three dimensions by imposing edge constraints on the simulated leaflets at their intersections with the support frame, whereinthe simulated support frame is tubular or frusto-conical, wherein the plurality of simulated leaflets are arranged in a tube or frusto-cone within the support frame, and wherein the edge constraints comprise a continuous line fixing the tube or frusto-cone of simulated leaflets around an inflow end of the simulated support frame, and a plurality of generally axial lines located at the intersections of adjacent axial edges of the simulated leaflets.
