32.7.9 Display/Options...

The Display/Options... menu item opens the Display Options panel.



Display Options Panel


The Display Options panel provides an interactive mechanism for setting attributes or options that control how and where a scene is rendered.

Controls

Rendering   allows you to modify characteristics of the display that are related to the way in which scenes are rendered. See Section  28.2.7 for details about these items.

Line Width   controls the thickness of lines. The default is 1.

Point Symbol   sets the symbol used for nodes and data points.

Wireframe Animation   uses a wireframe representation of all geometry during mouse manipulation This option is turned on by default. You should turn it off only if your computer has a graphics accelerator; otherwise the mouse manipulation may be very slow.

Double Buffering   turns double buffering on or off, if it is supported by the driver. Double buffering dramatically reduces screen flicker during graphics updates. Note that if your display hardware does not support double buffering and you turn this option on, double buffering will be done in software. Software double buffering uses extra memory.

Outer Face Culling   allows you to turn off the display of outer faces in wall zones. Outer Face Culling is useful for displaying both sides of a slit wall. By default, when you display a slit wall, one side will "bleed'' through to the other. When you turn on the Outer Face Culling option, the display of a slit wall will show each side distinctly as you rotate the display. This option can also be useful for displaying two-sided walls (i.e., walls with fluid or solid cells on both sides).

Hidden Line Removal   turns hidden line removal on or off. If you do not use hidden line removal, FLUENT will not try to determine which lines in the display are behind others; it will display all of them, and a cluttered display will result. You should turn this option off if you are working with a 2D problem or with geometries that do not overlap.

Hidden Surface Removal   turns hidden surface removal on or off. If you do not use hidden surface removal, FLUENT will not try to determine which surfaces in the display are behind others; it will display all of them, and a cluttered display will result. You should turn this option off if you are working with a 2D problem or with geometries that do not overlap.

Hidden Surface Method   chooses the method to be used for hidden surface removal. These options vary in speed and quality, depending on the device you are using. The choices are listed below.
Hardware Z-buffer   is the fastest method if your hardware supports it. The accuracy and speed of this method is hardware dependent.

Painters   will show fewer edge-aliasing effects than hardware-z-buffer. This method is often used instead of software-z-buffer when memory is limited.

Software Z-buffer   is the fastest of the accurate software methods available (especially for complex scenes), but it is memory intensive.

Z-sort only   is a fast software method, but it is not as accurate as software-z-buffer.

Graphics Window   allows you to open and close graphics windows. See
Section  28.2.2 for details.

Active Window   indicates the graphics window to be opened, closed, or set active. (A graphics window's ID is displayed in its title.)

Open/Close   opens or closes the window with the ID shown in the Active Window box. If the indicated window is open, the Close button will appear, and if the indicated window is not open, the Open button will appear.

Set   sets the window with the ID shown in the Active Window box to be the active graphics window. See Section  28.2.2 for details.

Lighting Attributes   controls lighting attributes for all lights in the active graphics window. See Section  28.2.6 for details.

Lights On   turns all lights in the active graphics window on or off.

Lighting   specifies the method to be used in lighting interpolation: Flat, Gouraud, or Phong. ( Flat is the most basic method: there is no interpolation within the individual polygonal facets. Gouraud and Phong have smoother gradations of color because they interpolate on each facet.)

Layout   controls the display of captions, axes and the colormap in the graphics display window. See Section  28.2.3 for details.

Title   enables/disables the display of all captions in the graphics display window.

Axes   enables/disables the display of the axis triad.

Colormap   enables/disables the display of the color scale.

Colormap Alignment   allows you to adjust the alignment of colormap in the graphics display. Select the side (i.e. Top, Bottom, Left, and Right) from the drop-down list, where you want to align the colormap.

Apply   applies the specified attributes and re-renders the scene in the active graphics window with the new attributes. To see the effect of the new attributes on other graphics windows, you must redisplay them.

Info   prints out information about your graphics driver in the console.

Lights...   opens the Lights panel, which allows you to create, delete, and modify directional light sources.
