摘要
文章总结了以往二维流场显示技术的特点,指出其不足。采用高效质点追踪算法,运用最新的软件编程技术,开发了拉格朗日法描述的二维非恒定流场动态模拟软件。软件图形编程基于GDI+,直接图形输出方式大大增强了动态显示的灵活性,先进的编程模式使得用户可在动态流场模拟同时控制显示方式,任意进行图形的平移、缩放操作,实现真正意义上的动态流场实时显示。
A program has been developed to animate the unsteady current with the efficient particle tracking methods.h calculates the velocity particles with Lagrangian method,and it is prograntaed with Visual C# based on Dot Net Framework.By using GDI＋ functions,the program has a lot of functional agilities such as translating, zoom in and zoom out to the graphics on the screen while animation is being processed.That ensures the real-time displaying of the current.
