Abstract:
1. A device for generating a mesh pattern formed of meshes for analysis, the device comprising: surface mesh generating means for generating a surface mesh pattern having quadrangular meshes, of an analysis object by acquiring shape model data on the analysis object and mesh control data including required quality of an analysis mesh model; internal mesh generating means for generating an internal mesh pattern of the analysis object in a six-plane body shape having eight mesh points according to the surface mesh pattern generated by the surface mesh generating means; quality evaluating means for evaluating quality of the surface mesh pattern generated by the surface mesh generating means according to the required quality, by determining internal angles of the mesh points of each mesh to the surface mesh pattern; and mesh correction means for shifting a surface mesh node point of a mesh not satisfying the required quality, according to the evaluation result obtained by the quality evaluating means, by selecting a node point of the mesh having an internal angle to the surface mesh, which deviates most from 90 degrees, and calculating a shift direction and a shift amount of the surface mesh node point to so that the internal angle of the selected node point to the surface mesh pattern approaches 90 degrees in an effort to improve the quality of the mesh pattern; wherein the internal mesh generating means, the quality evaluating means and mesh correction means repeat operations on a basis of a revised mesh pattern which incorporates the shift direction and the shift amount of the surface mesh node point.
