FLUENT 6 - Tip for displaying a velocity vector plot where the vectors are uniformly distributed on the displayed surface

In a velocity vector plot, one arrow will be displayed for every cell by default. As a result, the density of vectors will be directly proportional to the mesh density. If non-uniform mesh has been used, vector plot does not look very good: too crowded in one region and too coarse in anther. This solution provides a tip for displaying a uniformly distributed vector plot.
Procedures to generate a uniformly distributed vector plot:

Create a point-array surface by using the following text command: surface/point-array. You need to define coordinates of two diagonal points of a reactangle (the reactangle should be large enough to cover the entire cross-section of your cut plane) and the number of points you want to have in each direction. Once a point-array surface is defined, you can draw the vector plot on that surface. The point distribution in your vector plot will be uniform.
