面向对象的串并行有限元分析系统

研究了面向对象的串并行有限元分析系统的关键实现技术。首先介绍的有限元系统类库分析,重点阐明了面向对象方法应用于串并行有限元分析所具有的优势,基于此将集成系统归纳成多个组成类库:包括数学计算类库、数据处理类库、有限元基本类库、数值分析模型类库、图形类库以及应用框架工具类库等,进而介绍分析程序的面向对象实现方法及过程,最后形成一个集成的交互式并行有限元分析框架OOParaFEA(Object OrientedParallel FEA framework)。系统快速高效的实现,表明面向对象的方法的确从软件的可维护性、可扩充性以及减少复杂性等方面带来前所未有的优势,并且由于其固有的继承特性而使其特别适合团队协作开发大型有限元分析软件,从而给我国大规模科学计算软件的研制提供一个新思路。

Object-oriented serial/Parallel finite element analysis system

In this paper,some key techniques about object-oriented serial/parallel finite element analysis system have been explained.The FEA class library has been explained in detail at first,which focus on the advantages of OO(ObjectOriented) method applied in serial/parallel FEA,and based on the above class hierarchy map,the integrated system has been divided into several related parts which include mathematic class library,data managing class library,numerical analysis model class library,graphic class library and so on,then the object-oriented realization of linear/nonlinear,substructure method and serial/parallel analysis has been explained,in the end,integration method for the whole system is introduced.The realization of the above integrated system,OOParaFEA(Object Oriented Parallel FEA framework),takes much shorter time and get much higher efficiency than that of old way,that can show us that OO method can completely fulfill the requirements of developing large scale software system.The OOParaFEA can show some new ideas to make large scale parallel FEA software system.
