摘要:

基于面向对象的程序设计方法,以C++语言构造了自适应有限元P加密程序,它涉及到形函数的构造、高阶单元的形成、自升阶的算法以及误差估计一系列类及成员函数.解线性方程组时,根据P加密的特点,提出了一种节约存储和运算空间的数据结构.所给算例的计算结果表明,理论推导和程序实现是正确的.

关键词: 自适应有限元, P加密, 面向对象, 随机存储

Abstract:

Using C++ language with object-oriented feature, a P-version adaptive FEM program was designed, which contains the modules of shape function, high grade element, adaptive course and error estimate. In the function of solving linear equations, a data structure that can save storage space and computation resource was presented. The provided examples show the correction of the theory and program.

Key words: adaptive finite element methods, P-version, object-oriented, random storage
