| titleOfInvention | Tetrahedral lattice generation method and recording medium recording the program |
| abstract | (57) [Summary] [Problem] To provide a method for generating a three-dimensional Delaunay-divided tetrahedral grid by a simple algorithm that does not involve correction of the tetrahedral grid, and that can avoid failure in generating the tetrahedral grid. An advancing method in which lattice points are given in advance. Using the front method as the basic algorithm, a triangular lattice is first generated on the surface of the analysis area, and tetrahedral elements with each triangular surface as a side face are sequentially cut out to fill the analysis area. At this time, division into tetrahedral elements is not possible. In order to avoid the generation of a possible polyhedron region, a mechanism is provided to postpone the processing of a triangular surface that may generate such a polyhedron by using the means 6 for temporarily retreating the triangular surface, Even when six or more grid points are located on a spherical surface that does not include the grid points, there is provided a unit 8 that can divide the inside of the convex hull region into tetrahedrons without contradiction. |
