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