摘要/Abstract

摘要： 介绍了所研制的一个开源三维结构分析并行自适应有限元软件PHGSoIid。它是以并行自适应有限元软件平台PHG为基础开发的，支持在纯三维结构上进行并行自适应有限元分析。与现有的商业和开源结构分析有限元软件相比，PHGSoIid的特点和优势在于:1)支持完全自动化且高度并行的自适应有限元计算;2)能稳健高效地求解大规模问题，具有很好的计算规模可扩展性;3)易于扩展，用户可根据需要添加相应的计算模块。通过几个大型数值算例来展示该软件的计算能力和并行可扩展性，其中的最大计算规模超过了J亿自由度，最大并行规模达到了1024 个MPI进程。

Abstract: We presented our newly developed open source parallel adaptive FEM software for 3D structural analysis. It is based on the 3D parallel adaptive finite clement toolbox PHG. It features parallel adaptive finite clement analysis for pure 3D structures. It has several advantages over other structural analysis software. Firstly,it supports fully automatic and highly parallel adaptive FEM computations. Secondly, it is robust, efficient and highly scalable in solving large scale problems. Thirdly, the software is extensible, and users can conveniently add their own modules if needed. Several large scale numerical experiments demonstrate that the largest problem size of our software exceeds 500 million degrees of freedom and the largest number of MPI process reaches 1024.

Key words: 3D structural analysis, MPI, Parallel computing, Adaptive finite element method
