Step 9: Overlaying Velocity Vectors on the Pathline Display

Graphics and Animations

  The overlay capability, provided in the Scene Description dialog box, allows you to display multiple results on a single plot. You can exercise this capability by adding a velocity vector display to the pathlines just plotted.

1.   Enable the overlays feature.

Graphics and Animations Scene...

(a)   Enable Overlays in the Scene Composition group box.

(b)   Click Apply and close the Scene Description dialog box.

2.   Add a plot of vectors on the chip centerline plane.

Graphics and Animations Vectors Set Up...

(a)   Disable Draw Mesh in the Options group box.

(b)   Retain the value of 3.8 for Scale.

(c)   Deselect all surfaces by clicking the unshaded icon to the right of Surfaces.

(d)   Select fluid-sym from the Surfaces selection list.

  Because the mesh surfaces are already displayed and overlaying is active, there is no need to redisplay the mesh surfaces.

(e)   Click Display and close the Vectors dialog box.

(f)   Use the mouse to obtain the view that is shown in Figure  24.18.

Figure 24.18: Overlay of Velocity Vectors and Pathlines Display

Note:   The final display (Figure  24.18) does not require mirroring about the symmetry plane because the vectors obscure the mirrored image. You may disable the mirroring option in the Views dialog box at any stage during this exercise.
