摘要
本文给出了一种任意平面域内三角形网格自动生成及自动调整算法，并编制了相应的程序。通过对带Ｕ形槽的三点变曲试件的分析，证明本文算法是可行的，并且具有稳定性能好、收敛速度快的优点。
An efficient algorithm and programing scheme are presented for the automatic mesh generation ofarbitrary planar domains into triangular elements, which are based on the facts,1.arbitrary multiplyconnected regions can always be divided into triangular elements.2.active nodes in this region tend tozero with the generation of triangular elements.Methods for improving the quality of elements aregiven in this paper. The structure of this program has a well-knit plot with little input data, higherquality and stability.
