摘要: 传统的以串行计算机为物质基础的有限元算法分析未能满足科学研究和工程技术发 展的需要. 并行处理技术的发展为解决此类问题提供了新的契机. 机群式并行计算机是当今 较为流行的一种并行处理方式. 根据有限元法的特点,提出了一种并行有限元算法,并 在多处理机分布式内存并行计算机环境下完成了面向对象并行有限元程序的编制. 算例 表明该算法能大大提高其分析速度,而且算法简单,实现方便.

Abstract: Traditional FEM algorithm analysis for a serial processing computer can not satisfy the demand of scientific research and engineering technology development. Parallel processing technology provides a new prospect for solving this kind of problems. Cluster parallel computer uses a very popular parallel processing method at present. Based on the features of FE Method, this paper proposes a parallel finite element algorithm, together with an Object-Oriented FEM program under multi-parallel computers with distributing memory. The calculated examples show that this algorithm improves analyzing efficiency with simple organization.
