1. A three-dimensional model analyzing apparatus for analyzing a physical property of a three-dimensional model, comprising: an information receiving unit which receives information on a three-dimensional model as an object to be analyzed; an edge detecting unit which detects an edge of said three-dimensional model; a smoothing unit which smoothes said edge; and an analyzing unit which analyzes said three-dimensional model in accordance with a finite element method after said edge is smoothed by said smoothing unit.
