摘　　要：针对等参有限元的计算特点和有限元软件多种单元的开发需求,基于高性能计算程序开发框架Jaumin,使用面向对象语言,采用抽象和多态技术以及工厂模式,为有限元软件PANDA设计等参单元算法框架.该框架具有良好的可复用性及可扩展性,开发过程清晰,有利于提高开发效率.给出等参单元算法框架中各个模块所对应的类以及类的接口.实例表明用PANDA中已实现的等参单元计算结果与ANSYS的计算结果一致.As to the calculation characteristics of isoparametric finite elements and the development requirements of various kinds of elements in finite element software,based on the high performance computing program development framework Jaumin,an algorithm framework of isoparametric element is designed for the finite element software PANDA by abstraction and polymorphism technique and factory pattern using object-oriented language. The framework has good reusability and scalability,of which the development process is clear and can help to improve development efficiency. The corresponding classes and class interfaces of each module in the framework of isoparametric element algorithm are given. The examples show that the calculation results obtained by the isoparmetric element in PANDA is consistent with the results obtained by ANSYS.
