29.6.7 Adding a Bounding Frame

ANSYS FLUENT allows you to add a bounding frame around your displayed domain. You may also include measure markings on the bounding frame to indicate the length, height, and/or width of the domain, as shown in Figure  29.6.7.

Figure 29.6.7: Graphics Display with Bounding Frame

To add a bounding frame to your display, you will follow the procedure below:

1.   Click the Frame Options... button in the Scene Description dialog box (Figure  29.6.1) to open the Bounding Frame dialog box (Figure  29.6.8).

Figure 29.6.8: The Bounding Frame Dialog Box

2.   Under Frame Extents in the Bounding Frame dialog box, select Domain or Display to indicate whether the bounding frame should encompass the domain extents or only the portion of the domain that is shown in the display.

3.   In the Axes portion of the Bounding Frame dialog box, specify the frame boundaries and measurements to be shown in the display:

• Indicate the bounding plane(s) (e.g., the $x$- $z$ and $y$- $z$ planes shown in Figure  29.6.7) to be displayed by clicking on the white square on the appropriate plane of the box shown under the Axes heading. (You can use any of the mouse buttons.) The square will turn red to indicate that the associated bounding plane will be displayed in the graphics window.

• Specify where you would like to see the measurement annotations by clicking on the appropriate edge of the box. The edge will turn red to indicate that the markings will be displayed along that edge of the displayed geometry.

If you have trouble determining which square or edge corresponds to which location in your domain, you can easily find out by displaying one or two bounding planes to get your bearings. You can then select the appropriate objects to obtain the final display.

4.   Click the Display button to update the display with the current settings. If you are not satisfied with the frame, repeat steps 2 and/or 3 and click Display again.

5.   Once you are satisfied with the bounding frame that is displayed, click OK to close the Bounding Frame dialog box and save the frame settings for future displays.

6.   If you wish to include the bounding frame in all subsequent displays, turn on the Draw Frame option in the Scene Description dialog box and click Apply. If this option is not enabled, the bounding box will appear only in the current display; it will not be redisplayed when you generate a new display (unless you have overlays enabled).

The bounding planes and axis annotations will appear in the Names list of the Scene Description dialog box, and you can manipulate them in the same way as any other geometric object in the display. For example, you can use the Display Properties dialog box to change the face color of a bounding plane or to make it transparent (see Section  29.6.2).
