【摘要】 在Windows XP 64位操作系统环境下,利用若干普通PC机搭建了机群系统,实现了分布内存式并行(DMP)计算。采用3节点和4节点薄壳单元和2节点梁单元建立了约260万自由度(DOF)的全机有限元模型。采用封装的METIS区域分解方法(DDM),并利用大型通用有限元软件MSC.Marc,实现了全机静强度模型的并行求解,为大型复杂有限元模型的求解提供了一种高性价比的解决方案。更多还原

【Abstract】 In the Windows XP 64 bit operating system environment,several common PC is used to build a cluster system,realizing the distributed memory parallel(DMP) computing.A finite element model of whole aircraft with about 260 million degrees of freedom(DOF) is developed using three-node and four-node thin shell element and two-node beam element.Employing the packaged METIS domain decomposition method(DDM) and making use of the large universal finite element software MSC.Marc,this paper realizes the parallel solving of the static strength model of the whole aircraft,which offers a high cost-effective solution for solving large complex finite element models.更多还原
