摘　　要：有限元分析软件在船舶、汽车、航天、机械等领域具有广泛的应用;但商业性有限元软件还无法在国产超级计算机上安装。本文探讨了超级计算机和有限元软件相结合的几种方案;提出了基于系统集成思想的软件并行开发框架;在分析有限元分析并行计算重点的基础上,给出了该框架实现的原理和机制,以及相关的关键技术,从而为超级计算机应用软件的开发探索了一条新的途径。最后实现了一个实例系统,对基于系统集成思想的软件并行开发框架进行了实现和验证。Finite elements analysis softwares are applied widely in many fields including ship,auto,and so on.Trade finite elements softwares can not be installed on native supercomputers.Several combination schemes of supercomputers and finite elements softwares are discussed in this paper.A parallel development framework of softwares based on system integration thinking is presented.Based on the analysis of parallel computing emphases of finite elements analysis,principle and mechanism of the framework are given.Then corresponding key technologies are given.Thus a new approach was explored for development of supercomputer applications.Finally, an example system is implemented and the framework is validated.
