摘要
采用伽辽金有限元法(GAFEM)求解了一对线性椭圆边值问题的数值解。CLEBVP的解近似为分段线性和连续基函数的线性组合,将该近似解代入CLEBVP后,问题便简化为求解一个“伽辽金”线性代数系统(Galerkin linear algebra system, GALAS)。该系统采用经典的Cholesky方法(CChM)求解。给出了一些说明性实例;证明了GAFEM求解clebvp问题的高效率。图表向统计处提供“结果”。
Numerical Solution for Couple Elliptic Boundary Value Problem
The Galerkin finite elements method (GAFEM) is used to find the numerical solution (NS) of the couple linear elliptic boundary value problem (CLEBVP). The solution of the CLEBVP is approximated by a linear combination of piecewise linear and continuous basis functions, upon substituting this approximated solution into the CLEBVP the problem then reduces to solve a “Galerkin” linear algebraic system (GALAS). This system is solved by using the classical Cholesky method (CChM). Some illustrative examples are given; to show the high efficiency of the GAFEM to solve such for the CLEBVPs. Figures provide the NS with “results”.
