DAO动态绑定机制在非线性有限元分析程序中的应用

The Application of Dynamic Binding Mechanism of MFC DAO in Object-oriented Finite Element Program

运用有限元方法分析大型结构时,由于数据量巨大,其前后处理工作量相当可观,将数据库技术用于有限元数据的管理,能够大大提高后处理的效率。利用MicrosoftVisualC++的MFCDAO(数据库访问对象)所提供的动态绑定机制,可以大大提高有限元数据管理的灵活性。作者在开发非线性有限元分析系统的过程中,采用MicrosoftAccess2000关系型数据库为数据载体,文章详细阐述了MFCDAO动态绑定机制在有限元数据管理中的实现方法。

In the analysis of large-scale structures by finite element method,there can be a great amount of data,thus making it a tough task to perform postprocessing.The Dynamic Binding Mechanism(DBM)of MFC DAO(Database Access Object)provided by Microsoft Visual C++enables people to perform data processing of finite element analysis(FEA)in a very flexible way with high efficiency.This article creates a finite element analysis program employing Microsoft Access2000as its vehicle for data management ,and elaborates on the implementation of DBM in an object-oriented finite el-ement program.
