基于VTK的有限元计算结果可视化
首发时间:2008-10-09
摘要:有限元计算结果的可视化是分析有限元计算结果的重要手段。随着可视化的广泛应用,人们对于三维真实感图形的要求也逐步提高。为了便于使用,国内外推出了许多优秀的可视化软件。其中可视化工具包(Visualization ToolKit)是一个面向对象的可视化类库,它为从事可视化工具开发的广大科研工作者提供直接的技术支持。本文介绍了常用的可视化技术、VTK(Visualization ToolKit)特点及可视化流水线,数据流向。以Microsoft Visual C++ 6.0作为开发工具,结合VTK,编制了相应的可视化程序,基本实现了有限元计算结果(温度场、位移场、 应力场等)的可视化。最后给出了一个可视化的实例,成功地实现了云图、切割、流线、流面的显示。

Visualization of the FEM Results Based on VTK
Abstract:Visualization is an important method for analyzing FEM results.With the extensive use of Visualization, the demand of 3D realistic graphics is increasing. In order to be convenient for use, Many visualization software have been developed.Visualization Toolkit(VTK)is an object-oriented visualization class library. It provides technological support for those who work at visualization.The common Visualization Technology and the features, pipeline, direction of data flow of VTK are presented in this paper. Adopting Microsoft Visual C++ 6.0 as the development tool this article makes up the relevant visual program,which is relevant with VTK. FEM results visualization is also realized basically, such as temperature field, displacement field, stress field and so on. Finally a visualization example is given, and the Color mapping、Cutting、Streamlines、Streamsurfaces can be realized successfully.
