AutoCAD图形交换文件DXF在面向对象程序设计中的应用

An Object-Oriented program design of the finite element method by employ the AutoCAD Drawing Exchang file-DXF

  • 摘要: 利用FORTRAN90语言并结合AutoCAD图形交换文件DXF编制出一个面向对象的有限元程序, 执行该程序, 实现了包括网格自动生成、单元节点信息、等效节点载荷、约束条件及变形、等应力线图等前后处理的功能. 它克服了以往在有限元教学中面对大量数据需要输入和整理一大堆输出的结果数据, 做到了有限元前后处理的可视化, 让学生初步掌握有限元的面向对象编程的技术.

     

    Abstract: An object-oriented program of the finite element method was designed by utilising FORTRAN90 program language and conjugating with the AutoCAD Drawing Exchang file-DXF. Runing availabe program at present. We are implementing preprocessor and post-processing function, including mesh generation automatically, element-node informatiom,equivalent node forces,constrained condition and deformation, stress diagram etc. It overcome shortcomings of necessary of input a mass of date and treat output results date in past the FEM teaching. Meanwhile we attain aim of visibility about preprocessor and post-processing.Let students primary learn the FEM technical of Object-Oriented Programming.
