平面内的速度矢量是一组具有特定大小和方向的箭头。 The arrows are attached to discrete grid points in the plane. Using 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 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.
