Abstract

We have been developing an advanced general-purpose computational mechanics system, named ADVENTURE, which is designed to be able to analyze a three dimensional finite element model of arbitrary shape over 100 million Degrees Of Freedom (DOF) mesh. The one of main process modules for solid analysis, named ADVENTURE Solid, is based on the hierarchical domain decomposition parallel algorithm and employs the balancing domain decomposition as a solution technique for linearized equations. The ADVENTURE Solid has been successfully implemented on a single PC, PC clusters and MPPs with high parallel performances. Since the software has become a quite large system, it is not easy to install or operate the system on parallel machines by users. To solve this issue, in this paper, the main system including solver part is operated on the remote server like a cloud computing and to operate such a system from a client PC through the network, the Web-based CAE system is presented. As a large scale analysis, one model of 10 Million DOF is performed.

基于计算机网络的大规模问题并行CAE系统

我们一直在开发一种先进的通用计算力学系统，名为ADVENTURE，旨在能够分析超过1亿个自由度(DOF)网格的任意形状的三维有限元模型。实体分析的主要过程模块之一ADVENTURE solid基于层次域分解并行算法，采用平衡域分解作为线性化方程的求解技术。《ADVENTURE Solid》已经成功地在单个PC、PC集群和mpp上实现了高并行性能。由于软件已经成为一个相当大的系统，用户不容易在并行机上安装或操作系统。为了解决这一问题，本文提出了基于web的CAE系统，将包括求解器部分在内的主要系统像云计算一样在远程服务器上运行，并通过网络在客户端PC上操作该系统。作为大规模的分析，进行了一个1000万自由度的模型。
