A New Multigrid Method Based on Hierarchical Basis for the Finite Element Analysis

本文利用自适应有限元剖分和等级基技术 ,提出了一种新的等级基多重网格的分析方法 .由于该方法的限制算子R具有十分简单的表达形式 ,使得新方法的算法非常简单 。

According to the process of adaptive finite element analysis,a multigrid implementing method based on hierarchical basis is proposed.It can be implemented much easily due to rather simple form of the restrictor operator R used in the analysis.A test example shows that the present method possesses high computing efficiency.
