| Abstract: | 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. |
