面向对象的有限元程序设计

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 ,用链表方式实现结点、单元和材料的数据存放、用多态性实现单元的自由链接 ,方便的实现了单元增减等用传统语言无法实现的功能。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

Object-Oriented Finite Element Programming

In this paper 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 virtual element, node, material etc., have been developed and implemented using the object oriented programming language C . The elements, nodes and materials are stored by chain. Many type elements are stored in mix by polymorphism characteristics. The program is codified and an example is given to show the programming of finite element method.
