有限元编程中应用面向对象编程技术的探讨

摘要

采用面向对象编程技术（OOP），运用C++语言，描述了有限元程序的设计过程.针对有限元分析中的结点、单元和整个研究区域，建立了结点类、单元类和研究区域类分别负责管理，并提供了程序的部分实现代码.与传统Fortran语言编制的有限元程序相比，该法编制的程序执行速度快、维护简便、易于实现多种类型单元共存的情况，是解决大型有限元程序编制的有效方法.%The process of finite elements program design is described with C++ language and object-oriented programming(OOP).In the light of nodes,elements and the whole considered area at finite element analysis;the node class,element class and considered area class are established to be in charge of them respectively.Parts of the program codes are provided. Compared with finite element program with traditional Fortran language, the program with OOP has predominance of high speed in program running,convenient in maintenance and easily realizing coexisting of various kinds of elements. It is effective for large-scale finite element program design.
