面向对象的有限元程序设计

Object oriented finite element programming

本文按照面向对象的程序设计方法，遵循有限元分析的本质，采用Ｃ＋＋语言，建立了有关描述有限元模型的类，给出了类的描述和它的实现方法。相关的类和方法包括处理矩阵的类、节点类、单元类、材料类、形函数类等。据此编制了有限元分析的数值计算程序，并给出了一个实例。

The object oriented programming concept is applied to finite element method. According to the nature of the finite element analysis, the classes and their methods, which describe matrix, element, node, material, shape function etc., have been developed and implemented using the object oriented programming language C++. Program is implemented and a instance is given to show the programming of finite element method.
