| 摘 要： | 在常见的PC＋Windows＋LAN环境下，采用Winsock API网络通信接口实现了局域网上的分布式并行有限元网格生成。网格生成区域在服务器上按照工作站数量被分解为若干个子区域，这些子区域及网格控制参数通过局域网（LAN）传给工作站。子区域在工作站上被剖分成子网格并通过局域网传回服务器以合并形成最终网格。算例表明只要有足够的计算节点，分布式并行技术可以将网格生成速度大幅度提高，而网络通信所占时间的比例基本固定。

| Abstract: | A distributed parallel FEM mesh generator was developed on a general environment of PC+Windows+LAN.WinSock API of MFC was applied for network communications.The whole region was divided into several subregions on server according to the number of workstations on network.The server sent information of the subregions and control parameters to each workstation.Then the subregions were meshed into elements on the workstations which also fed back the mesh data to the server.Finally,the server merged the mesh of each subregion and gave the final mesh of the whole region.Example shows the speed of mesh generation increases drama-tically with enough workstations,and the ratio of time consuming on network communications is almost fixed. |
