摘要:
 科学计算可视化自提出至今已在许多研究领域得到了广泛应用，计算流体力学( CFD)可视化正是其中之一。文中首先简要介绍了可视化工具库( VTK)及其流水线结构，之后介绍了计算流体力学软件的基本架构。在此基础上，以均匀流场网格为例，讨论了使用VTK进行流体可视化开发的通用流程。最后在团队开发的基于LBM方法的CFD软件基础上，实现可视化模块，包括基本标量属性(压力、温度等)的颜色映射，流体网格的内部切面以及流线方式的速度矢量可视化。同时展示了以上可视化方法的模拟结果。可视化模块与前处理和求解模块共同组成整个CFD软件，并通过图形结果直观地展示流场内部粒子的属性和运动规律。
Abstract:
 Visualization in scientific computing has been widely used in many fields of scientific research since it was put forward,the Computational Fluid Dynamics ( CFD) visualization is just one of them. In this paper,firstly present a brief introduction to the Visualiza-tion ToolKit ( VTK) and the architecture of its pipeline,basic framework in CFD software. After what is discussed in the sections above, describe the common process of CFD visualization using VTK. Finally,add the visualization functions on the CFD software developed by the team based on LBM method. Visualization functions including color mapping of scalar properties such as pressure,temperature,etc, cut surface in the fluid grid and vector properties of velocity in the manner of streamline are realized. Visualization module constitutes the entire CFD software with pre-propose and resolver module,and shows the properties and law of motion of particles in the fluid field intu-itionally.
