Step 5: Contours

Graphics and Animations

1.   Display filled contours of temperature on the symmetry plane (Figure  24.6).

Graphics and Animations Contours Set Up...

(a)   Retain the default settings in the Options group box.

(b)   Select Temperature... and Static Temperature from the Contours of drop-down lists.

(c)   Select board-sym, chip-sym, and fluid-sym from the Surfaces selection list.

(d)   Click Display.

(e)   Rotate and zoom the display using the left and middle mouse buttons, respectively, to obtain the view as shown in Figure  24.6.

Hint:   If the display disappears from the screen at any time, or if you are having difficulty manipulating it with the mouse, you can open the Views dialog box by clicking the Views... button in Graphics and Animations task page and use the Default button to reset the view. Alternatively, you can revert to a previous graphics display using the keyboard shortcut <Ctrl>-L.

  The peak temperatures in the chip appear where the heat is generated, along with the higher temperatures in the wake where the flow is recirculating.

2.   Display filled contours of temperature for the clipped surface (Figure  24.7).

Graphics and Animations Contours Set Up...

(a)   Deselect all surfaces from the Surfaces selection list and then select fluid-sym-x-clip and fluid-sym-y-clip.

(b)   Click Display.

(c)   Orient the view to obtain the display as shown in Figure  24.7.

3.   Display filled contours of temperature on the plane, y=0.25in (Figure  24.8).

Graphics and Animations Contours Set Up...

(a)   Deselect all surfaces from the Surfaces selection list and then select y=0.25in.

(b)   Click Display and close the Contours dialog box.

4.   Change the location of the colormap in the graphics display window.

Graphics and Animations Options...

(a)   Disable Axes in the Layout group box.

(b)   Select Bottom from the Colormap Alignment drop-down list.

(c)   Click Apply and close the Display Options dialog box.

(d)   Zoom the display using the middle mouse button to obtain the view as shown in Figure  24.8.

Figure 24.8: Temperature Contours on the Surface, $y$ = 0.25 in.

  In Figure  24.8, the high temperatures in the wake of the module are clearly visible. You can also display other quantities such as velocity magnitude or pressure using the Contours dialog box.

5.   Change the display of the colormap labels.

Graphics and Animations Colormap...

(a)   Ensure that Show All is disabled.

(b)   Set Skip to 2.

  It can also be observed that the contour labels are crowding the bottom of the screen, where the colormap is displayed. You can control the number of labels displayed on colormaps by using the skip-label function.

(c)   Click Apply and close the Colormap dialog box.

  The display updates immediately with every other colormap label appearing, as shown in Figure  24.9.
