This paper applies Advancing Front Technique ( AFT ) and background method in adaptive finite element mesh generation based on re-meshing. High-quality mesh generation technique and the element size computation method are two key issues to adaptive mesh generation. 在基于重生成的自适应有限元网格生成算法研究中,将推进波前法(AFT)与背景网格法结合并提出改进方法,有效地解决了网格生成和单元尺寸计算这两个关键问题。
