计算流体力学可视化功能的实现

The Realization of Flow Visualizationin Computational Fluid Mechanics

利用计算机图形学的理论和方法，并借助于ＮＤＰ－Ｆｏｒｔｒａｎ编译系统的图形功能，开发了计算结果的事后式可视化软件，包括计算区域网格图的绘制，速度矢量图绘制，温度等标量的颜色显示，以及曲线图的输出等．为进一步优化所开发三维复杂区域对流换热场的数值计算程序，使之应用方便，在程序中加入了驾驭式可视化功能，即除能在不终止计算的情况下，以图形方式显示及输出中间计算结果外，还能调整计算参数，以控制数值计算进程．

This paper developes the visualization software for viewing the computational results bymeans of the principles and methods of computer graphics and with the aid of the graphicalfunctions of the NDP-Fortran compiler,which includs the grid,vector and scaler displays andgraph output, etc. In order to further improve the computational program with natural andforce convection in 3D complex geometries and make it easy to use,the mid-results are shownwith images and the computational parameters are adjusted during the computing processes.
