ICCG算法在SF6罐式高压断路器三维电场有限元计算中的应用
THE APPLICATION OF ICCG ALGORITHM IN THE THREE DIMENSIONAL ELECTRIC FIELD CALCULATION OF SF6 TANK-TYPE CIRCUIT BREAKER
摘要
Abstract
The incomplete Cholesky-conjugate gradient method(ICCG) applied to solve large sparse matrix was analyzed in this paper. The general ICCG pointer memory addressing was studied and new data structure was adopted. The method of general ICCG pointer memory addressing based on the mesh generation data was given. It can solve the addressing problem of coefficient matrix effectively and rapidly. The three dimensional electric field between the tank-type circuit breaker's contacts was computed by using isoparametric finite element method and the large sparse matrix was solved by using ICCG algorithm.关键词
