【Abstract】 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.更多还原
