摘要
基于协调三角形剖分算法、分子表数据结构和Zienkiewicz-Zhu误差估计方法,本文研制出适用于自适应多重网格有限元的网格生成器。该网格生成器可对复杂的区域进行自适应加密。当荷载作用边界随时间变化及在动力荷载作用下,网格生成器可退化与再加密网格。
Based on conforming triangulation algorithms、the molecular list structure and Zienkiewicz-Zhu error estimation,a mesh generator suitable for adaptive multigrid finite ele- ment method is implemented in this paper. The mesh generator can be used to refine complex region adaptively.As the load boundaries vary with time and under the dynamic loads.the meshes can be further refined or dis-densified.
