二维四边形单元的自动生成研究

Research on 2 - D Automated Quadrilateral Mesh Generation

提出了任意二维区域的全四边形网格生成方法。该算法允许在区域边界上具有不同的单元尺寸，生成的网格具有较少的不规则节点和良好的全局形状质量。在边界上单元具有良好的形态，充分满足了有限元分析对边界上单元形状的要求。最后用算例进行了证明。

A new mesh generation algorithm which meshes arbitrary 2 - D geometries with an all-quadrilateral mesh is presented and it allows distributions of varying element size on the boundary. The generated mesh is well formed and geometrically pleasing, and mesh contours closely follow the contours of boundary. At the end of this paper we present an example of automatically generated meshes.
