摘要
本文利用图论知识和RCM算法,对有限元加密网格的节点进行编序优化,从而得到总刚矩阵带宽极小和元素贮存量极少的单元节点新编码图.此方法概念清楚,程序结构简单,应用方便.
In this paper, the graphic theory and RCM algorithm method areused to optimizing the node on the mesh of the finite element refinement. And by this waythe new coding figure of the extreme small band wideness or the assemble stiffness matrixand the least store amount or the matrix element is obtained. This method is clear in itsidea and simple in its program structure and convenient in using.
