中文摘要：

针对二维弹塑性流体力学非结构网格拉氏应用程序（LSPIC）,应用双线性插值、点排序和网格排序三种方法对计算区域进行分解。基于格式所需邻区网格的个数实现区与区之间的消息传递,建立一种非结构网格拉氏程序并行化方法,实现二维弹塑性流体力学拉氏应用程序（LSPIC）程序的并行化。同时进行程序测试和并行效率分析。

英文摘要：

For LSPIC,the paper applies bilinear interpolation,node sorting and mesh sorting to decompose the computation region,on account of the number of neighboring meshes required by format,realizes messaging among regions,and builds an unstructured meshes Lagrange program paralleling method to realize LSPIC program parallelization.Meanwhile program testing and parallel efficiency analysis are performed.
