摘要
本文提出了有限元直接迭代算法。推导出了直接迭代格式的统一公式,并给出了几种网格剖分方式下的有限元直接迭代格式的具体形式,讨论了各剖分方式的优劣。
The direct iterative algorithm of the finite element is presented. The general iterative formula of it is deduced. At the same time, the concept of the essential structure, essential structure ordinate and general ordinate is formulated. Several kinds of concrete iterative forms are given based on different grids and the difference of them are discussed. The program of this algorithm has been finished, and exemplified.
