摘　　要：在力学及应用数学中 ,有多种非线性问题 ,用BEM (BoundaryElementMethod)对它们进行分析时 ,数据处理比较复杂。由于在场方程中往往同时存在非线性项 ,线性项和非齐次项 ,使得误差来源往往判断不准 ,本文针对不同的类型建立若干源库 ,再建立相应的数据总库及数据处理库 ,用命令文件完成数据传输及数据处理 。There are many nonlinear problems in mechanics and applied mechanics.BEM being used in these problems,data processing is very complicated.Because of coexistance of nonlinear and linear terms as well as nonhomogeneous terms in field equation,we hard to judge the origin of error.In this paper,we established several source library pointing to different types,established corresponding data bank,data processing base and then completed data transmission and data processing by means of command file.when all these are done we con solve above problems by BEM.
