Velocity Vectors
The velocity vectors within a slicer plane represent a collection of arrows featuring specific magnitudes and directions. The arrows are attached to discrete grid points in the plane. By the velocity vectors, you can evaluate both the wind speed and the direction of air flow around the model.
To display velocity vectors at specific sections through the model, use the Slicer options described in the Chapter 'Slicer'.
The View navigator provides three options for you to modify the vector display: Line (shows or hides vector lines), Arrow Head (shows or hides vector heads), Uniform Size (scales or levels vectors). If the latter option is disabled, the arrow lengths and thicknesses of heads reflect the magnitudes of each wind velocity.
