| 摘 要： | 针对多连通区域,利用虚边界元思想进行程序实现时,数据文件的准备工作十分重要.多连通区域数据文件输入时,虚、实边界的外、内边坐标点及实边边界条件的正负号应严格保证正确性.本文用FORTRAN语言实例分析承受均匀内、外压的厚壁圆筒,虚体积力等额配点离散其边界,提出边界离散坐标点输入及实边边界条件正负号的处理方法.

| Abstract: | In virtual boundary programming,the preparation of the document of data is very important.The data of multiple-connected region inputted,coordinates of outer,inner edge points in both virtual and real boundaries,and positive and negative number of real edge boundary conditions should be guaranteed.Through the analysis of thick wall cylinder under uniform internal and external pressure,using the method of virtual volume force element-equivalent collocation method to discrete.The coordinates of points and pos... |
