摘　　要：基于UG(Unigraphics NX)软件开发了针对二维边界元法的前处理模块,该模块使用UG开放应用程序接口(UG open application programming interface,UG/Open API)实现UG软件与边界元法前处理模块的交互,开发了可视化的用户界面(user interface,UI),通过该界面可实现模型读取、网格划分、边界条件加载等一系列前处理功能,最终可导出前处理数据,供边界元法程序直接计算。与边界元法计算程序相结合,对二维问题的大坝进行了静力分析,并与有限元法的计算结果进行了对比。This study develops a pre-processing module for two-dimensional boundary element method(BEM)based on Unigraphics NX(UG)software.The module uses UG open application programming interface(UG/Open API)to realize the interaction between UG software and BEM pre-processing module,and a visual user interface(UI)is developed,through which a series of pre-processing functions such as model reading,grid division and boundary condition loading can be realized.Finally,the pre-processing data can be derived for direct calculation by the BEM program.Combined with the program of BEM,the static analysis of dam with two-dimensional problem is carried out in this paper,and the results are compared with those of finite element method.
