Abstract: A structural analysis program which enables easy structural analysis in accordance with a finite element method based on data representing a two-dimensional shape. A two-dimensional model of a structure is produced in response to a manipulation input which designates a material arrangement pattern and a thickness of each layer of the structure. A three-dimensional model is produced by adding the designated thickness of each layer to the material arrangement pattern of the layer so as to make the material arrangement pattern three-dimensional and stacking the three-dimensionalized material arrangement pattern of each layer. A finite element model is produced by dividing the three-dimensional model into a plurality of voxels. The computer performs structural analysis based on the produced finite element model. Thereby, an analysis result of a multilayer structure defined by the two-dimensional model is obtained.

Abstract: Three-dimensional (3D) image comparison program, method, and device are provided to identify and display differences between given 3D images more quickly and accurately. A computer produces a 3D differential image by comparing given 3D images after converting them into voxel form. With respect to a surface voxel of the 3D differential image, the computer produces a 3D fine differential image containing fine-voxel images that provide details of the original first and second 3D images at a higher resolution than that of the 3D differential image. Subsequently, the computer determines a representation scheme from differences between the first and second 3D images by comparing their respective fine-voxel images. The computer outputs voxel comparison results on a display screen or the like by drawing the 3D differential image, including the surface voxel depicted in the determined representation scheme.
