| 摘 要： | 提出了基于四叉树和三角化方法的一种简单，快速且有效的平面结构区域内网格自动生成方法。该方法既可以生成全三角形或全四边形单元，又可以生成二者共存的混合型单元网格，还可以根据实际需要，特别是有限元网格的要求，产生尽可能多的正方形与矩形单元。 |
| 关 键 词： | 有限元 网格 优化 映射 |

| Abstract: | A simple, speedy but efficient algorithm for automatic mesh generation over arbitrary polygonal domain is proposed in this paper. The algorithm can not only generate all triangular meshes and all quadrilateral meshes but also generate mixed mode meshes consisting of both quadrilateral and triangular elements. Besides, according to actual need, especially the demand of finite element meshes, it can generate rectangles or squares as many as possible. The methods of extruding, revolving and plane slicing to generate meshes for spatial solid structure are also investigated. The methods given can be applied to the automatic structural mesh generation in structural parts simulation design, mechanical analysis etc. So the methods discussed in the paper are very convenient to use. They will have good application value. |
