本文描述了一种自动的二维四边形单元网格生成器的研制。该方法基于M.L.C.Sluiter博士部分开发的循环算法。贝塞尔曲线用于定义要网格化的零件的边界。用户所需的交互减少为指定边界几何形状、优选的单元大小和细化系数。过渡元素在不同元素大小的区域之间自动生成。偏移指定边界曲线的能力确保了边界上条件良好的元素。为了说明网格生成器的通用性，给出了几个样本几何形状的网格。
This paper describes the development of an automatic, two-dimensional, quadrilateral element mesh generator. The methodology is based on the looping algorithm developed in part by Dr M. L. C. Sluiter. Bezier curves are used to define the boundaries of the parts to be meshed. The required interaction by the user is reduced to specifying the boundary geometry, the preferred element size and the refinement coefficient. Transition elements are automatically generated between regions of varying element sizes. The ability to offset specified boundary curves insures well-conditioned elements along the boundary. Meshes for several sample geometries are presented to illustrate the versatility of the mesh generator.
