固体力学边界元分析程序包BESMAP——基本结构功能

THE BASIC STRUCTURE AND FUNCTIONS OF A NEW BOUNDARY ELEMENT ANALYSIS PACKAGE "BESMAP" FOR SOLID MECHANICS ANALYSIS

要使边界元法象有限元法那样得到广泛应用,必须开发与有限元法相媲美的大型边界无法程序包。国外虽出现少数几个边界无法程序包,但由于结构、功能等方面的原因,还不能成为边界元法广泛应用的工具。针对这种情况,本文借鉴现有的先进的有限元法程序包,研制了大型固体力学边界元法程序包BESMAP,BESMAP在总体设计、计算能力、使用方便和功能齐全等方面作了研究和改进。

In order to apply the boundary element metnod as popularly as the finite element method, it is necessary to develop the boundary element analysis packages competively effective as the finite element analysis packages. Internationally, there are some boundary element analysis packages have been developed; however, their structures and functions are not very perfect, which fact affects its popularity. For this reason, on the basis of past experience of computational mechanics, we have developed a new boundary element analysis package for solid mechanics BESPAP which has new structural design, good computional capabilities and ease for use.
