firstly, by combining the modem computer software technique ( object oriented component program design method ) and the fem method of the civil engineering structure analysis, the application frame design of the object oriented paralleling fem is explored and under research in the structural analysis field of the civil engineering which has important influence on the national economic . secondly, one fem paralleling application system in net environment based on dcom is realized . finally, a parallel solver of the linear equations has been developed successfully 针对以上现状,本文的思路是:利用最新的计算机软件技术(基于面向对象的组件化程序设计方法)结合土木工程结构分析的有限单元法,研究和探讨了面向对象有限元并行应用框架设计,在此基础上基于dcom技术实现了一个在网络环境下的有限元并行应用系统,最后编制了一个求解线性方程组的并行求解器。
