Patent ID: 7395190

Claim:
An analytical model producing apparatus comprising: means for entering a shape model to be analyzed; a database which maps each of a plurality of shape models previously made together with analytical hexahedron mesh models corresponding to the shape models previously made; a degree of approximation calculating means including: means for producing associated information of shape elements by comparing shape elements in the shape model to be analyzed with shape elements in the shape models previously made and associating the shape elements in the shape model to be analyzed with the shape elements in the shape models previously made, means for calculating a degree of approximation of the shape elements of the shape models previously made based on the number of shape elements of the shape model to be analyzed and the number of shape elements of the shape model previously made associated with the associated information of the shape elements, means for displaying sequentially the shape models previously made from larger to smaller degrees of approximation on a display screen, and means for selecting, in response to an instruction, at least one of the shape models previously made from among said shape models previously made displayed; and an analytical model producing means for producing an analytical hexahedron mesh model of the shape model to be analyzed which has a number of divisions of a ridge and a direction of ridge arrangement corresponding to the number of divisions of the ridge and the direction of ridge arrangement of said shape model previously made selected by the means for selecting, in accordance with the associated information of the shape elements between the shape elements in the shape model to be analyzed and the shape elements in the shape models previously made.
