Complex structure of the finite element analysis of the need to spend enormous time and computer memory. During this process, the finite element of linear equations to solve a significant proportion of the time, therefore, the development of efficient algorithm for solving linear equations is to improve the efficiency of finite element analysis of the key. Against matrix inverse problems, this article will FEM equation as the coefficient matrix sub-block matrix and sub-block matrix based on the concept of promoting the traditional inverse matrix of 2 n n factor and product form factor. After the promotion of this group are in the form of the product under appropriate conditions and degradation were to be the inverse of traditional Matrix 2 n n factor and product form factor. After the application based on the promotion of this group are the product of the inverse form of algorithms to solve sheet metal stamping finite element simulation of large-scale finite element of linear equations, the results show that the algorithm can significantly improve the large-scale finite element of linear equations Solving efficiency.
