Patent ID: 6965688

Claim:
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 transforms said edge into a curved surface having a predetermined radius of curvature; 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 and after dividing the three-dimensional model into a plurality of hexahedral elements which are formed with edges each having a length shorter than said predetermined radius of curvature; and a number-of-divisions varying unit which varies the number of said plurality of hexahedral elements, wherein said analyzing unit determines a converged value of a physical quantity based on a local maximum of calculated values of said physical quantity which are obtained while increasing the number of said plurality of hexahedral elements by said number-of-divisions varying unit.
