FORTRAN与AutoCAD的接口软件设计及其在有限元分析中的应用

Interface design of FORTRAN and AutoCAD and its application in finite element analysis

针对有限元分析原始数据量大和检查这些数据的正确性繁杂耗时的问题 ,利用VisualFortranPowersta tion4 .0编写与AutoCAD接口的子程序 ,将有限元分析的原始数据可视化 ,以便于结构分析人员检查数据的正确性 .图形平台利用了工程技术人员所熟悉的AutoCAD平台 ,在图形显示方面 ,利用了DXF数据接口 ,使图形不经任何转换可以跨平台显示 ,而且图形的生成速度快 ,适合于数据量大且结构复杂的空间结构 .

Aiming at the problems met during finite element analysis such as great amount of initial data and complicated time consuming work of data validity inspection, those initial data are made visualized by using visual Fortran Powerstation4.0 programming for the use by the persons of struction analysis. The Platform AutoCAD familiar to technical personnel is taken as graphics platform and the data interface DXF is used as graphics displaying, so that the graphics could displayed across the platform without any transformation. Besides the graphics generation is fast and suitable for the special pale system construction with great amount of data and structural complexity.
