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 Release 13.0 - © SAS IP, Inc.

14.5. Isosurface Techniques Isosurface displays are surfaces of constant values (for example, stress). To obtain an isosurface display of von Mises stress, perform these steps: 1. Issue the command /CTYPE,1 (Utility Menu> PlotCtrls> Style> Contours> Contour Style). 2. Issue the command PLNSOL,S,EQV (Main Menu> General Postproc> Plot Results> Contour Plot> Nodal Solu). You can animate isosurfaces. To do so, either invoke the ANISOS macro (Utility Menu> PlotCtrls> Animate> Isosurfaces). 14.6. Controlling Particle Flow or Charged Particle Trace Displays You can produce graphic displays of how a particle travels in a flowing fluid or how a charged particle travels in an electric or magnetic field. See The General Postprocessor (POST1) for more information on graphic displays and see Animation (p. 267) for information on particle trace animation. See the Theory Reference for the Mechanical APDL and Mechanical Applications for simplifying assumptions on electromagnetic particle tracing. To produce particle flow or charged particle trace displays, use either of the following: Command(s): PLTRAC GUI: Main Menu> General Postproc> Plot Results> Plot Flow Tra Utility Menu> Plot> Results> Flow Trace Main Menu> General Postproc> Plot Results> Particle Trace Utility Menu> PlotCtrls> Animate> Particle Flow Such displays require you to select the trace points by number or by picking. To select points, use either method shown below: Command(s): TRPOIN GUI: Main Menu> General Postproc> Plot Results> Flow Trace> Defi Trace Pt You can list or delete these points using the commands shown below: 14.6. Controlling Particle Flow or Charged Particle Trace Displays Command(s): TRPLIS GUI: Main Menu> General Postproc> Plot Results> Flow Trace> List Trace Pt Command(s): TRPDEL GUI: Main Menu> General Postproc> Plot Results> Flow Trace> Dele Trace Pt Use either of the following to animate the particle flow or charged particle trace to a specified elapsed time. Command(s): TRTIME GUI: Main Menu> General Postproc> Plot Results> Flow Trace> Time Interval Release 13.0 - © SAS IP, Inc.
