摘要
这里采用数据结构理论探讨了一种基于C++Builder界面下的计算机网格图形数据转换实现方法,并设计开发了一个有限元前置数据格式转换的人机交互式应用程序。应用响应面插值理论,建立了空间有限元网格内点函数的插值算法,获得的空间响应面节点函数数据可直接应用Tec-plot软件进行复杂函数显示,有效的实现了有限元后置结果可视化处理。
A graphical data converting technology for computer drawing is researched through data - structure interfrace programming of C ＋ ＋ builder in this paper. The applied software to transform finite - element mesh （FEM） data is developed with C ＋ ＋ in four steps, that is, requirement analyisis, concept design, logic design and code programming. The paper employs mathematical response surface fitting method to obtain a continuously spatial data inside ofmeshe, and then calculates the nodal function values of meshes by interpolation or extrapolation, as results of which shows excellent effect of displaying complicated functions and graphically post - process FEM discrete numerical results.
