| 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。

| 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 uni- versal 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. |
