| 英文摘要 | Body-fitted grids have a wide application prospect in numerical simulation of geology. In order to solve the boundary discrete problem in generation of body-fitted grids, we put forward the maximum length criteria and the maximum area criteria which transform the curve approximation and the surface grid optimization problems into a mathematical optimization problem. We further propose a single particle optimization algorithm for solving this problem. Tests show that the maximum length criteria and the maximum area criteria have better optimization effects than the conventional methods. The calculation efficiency of the improved single particle optimizer is thirty times of the intelligent single particle optimizer (2 0 0 nodes) when solving this problem, and it achieves the application goal of the maximum length criteria and the maximum area criteria in generating body-fitted grids. Because the maximum area criteria cannot control the grid step length, we propose a limited step length grid optimizer which makes the step length more reasonable. We have tested and verified the effectiveness of this algorithm. The research results provide boundary optimal criteria and the solutions, which have important significance in generating body-fitted grids with complex boundaries in the future. |
