渗流问题的边界元方法比较

摘要

The boundary element method only divides the element on the boundary so that it can reduce to one dimension for calculation and fits to solve infinite domain and has the advantage to solve the problem of seepnge. This paper introduces three calculation methods of boundary element and using different methods to calculate the same example for comparison. The results showed that using the boundary point method to calculate seepage problem has the advantage of easy calculation program, high calculation accuracy, and easy to master and extend.%由于边界元法只在边界上划分单元,因而可降低一维进行计算,且适合解决无限域问题,在渗流研究中具有独特的优点.为此,简要介绍边界元三种计算方法,并采用不同的方法对相同的算例进行计算比较.结果显示,采用边界点方法处理渗流问题,具有计算程序简单.且计算精度较高的优点.易被工程人员掌握和推广.
