Chapter 14: Creating Geometric Results Displays
Driver
Contour Display
The X11C driver (screen dis- If eight graphic planes are available, you can specify any number of contours,
play) in either vector or raster up to 128. If your display device does not support eight graphic planes, you
mode are limited to displaying nine contours. If another process has used some of
the colors, making fewer than eight graphic planes available, you cannot display
more than nine contours. (To verify how many graphic planes are available,
issue the /PSTATUS command after a plot command.) To make more graphic
planes available, you must exit from the ANSYS program, re-enter, and then
issue the /SHOW,X11C-FORC to force selection of the full set of eight graphic
planes.
Plotting to an ANSYS neutral
graphics file
Note
Nine contours are the maximum, unless you specify the contour range (using
VMIN and VMAX in the /CONTOUR command), or unless you explicitly set
NCPL to 8 on the /SHOW command).
If the current ANSYS graphics are not displayed as Multi-Plots (Utility Menu> Plot> Multi-Plots),
then the following is true:
If the current device is a 3-D device [/SHOW,3D], the model contours in all active windows will be the same,
even if separate /CONTOUR commands are issued for each active window.
For efficiency, ANSYS 3-D graphics logic maintains a single data structure (segment), which contains precisely
one set of contours. The program displays the same segment in all windows. The view settings of each
window constitute the only differences in the contour plots in the active windows.
14.4. Q-Slice Techniques
Q-slicing is a technique you can use to query the interior or your model via slice planes. To implement Qslicing,
change the hidden surface type to Q-slice using either of these methods:
Command(s): /TYPE,1,8
GUI: Utility Menu> PlotCtrls> Style> Hidden-Line Options
By default, the slice plane is perpendicular to the view and is positioned at the focus point. You can set the
slice plane via the GUI path shown above or by using the /CPLANE,1 command.
To position the working plane, you can use either of these methods:
• Choose Utility Menu> WorkPlane> Align WP with> Keypoints.
• Click on the dynamic mode button in the Offset WP menu. To access this menu, choose Utility Menu>
WorkPlane> Offset WP by Increments.
You can animate Q-slices. To do so, choose either of these GUI paths:
GUI:
254
Utility Menu> PlotCtrls> Animate> Q-Slice Contours
Utility Menu> PlotCtrls> Animate> Q-Slice Vectors
