Chapter 14: Creating Geometric Results Displays 14.3.2. Controlling Vector Symbols in Your Results Display You have two options for controlling vector symbols: • Displaying nodal or reaction force symbols. You can add arrow symbols representing nodal and reaction forces (and moments) to your results display with the /PBC command (Utility Menu> PlotCtrls> Symbols). • Vector length scaling. You can control the lengths of vector symbols (such as are displayed by PLVECT or /PBC) with either of the following: Command(s): /VSCALE GUI: Utility Menu> PlotCtrls> Style> Vector Arrow Scaling 14.3.3. Controlling Contour Displays When light-source shading is on, the colors shown in the contour legend will not exactly match the contour colors used in the shaded model display. You can manipulate contour displays in the following ways: • Labeling contours. In both vector and raster mode, your contours will always be automatically colorcoded. In vector mode, you can add alphabetic contour labels (and a contour legend), using the /CLABEL command (Utility Menu> PlotCtrls> Style> Contours> Contour Labeling). In raster mode, /CLABEL will add (or remove) the contour legend. • Controlling the contour legend. Sometimes, lengthy text in the legend column can cause part of the contour legend to be truncated. You can make more room available for the contour legend by issuing /PLOPTS,LEG1,0 (Utility Menu> PlotCtrls> Window Controls> Window Options). To remove the contour legend from the legend column, issue /PLOPTS,LEG3,0. • Changing the number of contour labels. In vector mode, if you apply contour labels, they will, by default, appear in every element crossed by a contour line. You can use /CLABEL to control the number of alphabetic contour labels per element. • Changing contour colors. To change the contour colors used in your display, create a new color-map file and read the new color-map file using one of the following: Command(s): /CMAP GUI: Utility Menu> PlotCtrls> Style> Colors> Load Color Map To restore color to contours that are grayed out, issue the command /NUMBER,0. Note For 2-D drivers (especially Win32c), modifying the color map can produce anomalies, including legend/contour disagreement. • Changing isosurface colors. Using the ISURF label in the /COLOR command (Utility Menu> PlotCtrls> Style> Colors>color type) enables you to change isosurface colors. • "Inverting" (or reversing) the contour colors. By default, the ANSYS program displays the algebraically greatest results values with a bright red contour color, and the algebraically lowest values, with a blue contour color. In some cases, you may want to invert this order. You can create a reversed color-map file by using the CREATE option of the /CMAP command. You can then read that reversed color map file into the database, also with the /CMAP command. 252 Release 13.0 - © SAS IP, Inc.

• Changing the contour interval. To change the contour interval on your results display, either issue the /CVAL command (Utility Menu> PlotCtrls> Style> Contours> Nonuniform Contours) or the /CONTOUR command (Utility Menu> PlotCtrls> Style> Contours> Uniform Contours). These commands change the range of values displayed in contour displays. /CONTOUR produces uniform contour intervals, while /CVAL produces specified contour values (which need not be uniform). If you issue both commands, the program uses the last one specified. For related information, see Section Changing the Number of Contours (p. 253). • Topographic contour displays. You can transform "flat" contour results displays into "3-D" topographic displays with the /SSCALE command (Utility Menu> PlotCtrls> Style> Contours> Contour Style). • Displaying numerical results values. To display results values at each node in a contour display, issue /PNUM,SVAL,1 (choose Utility Menu> PlotCtrls> Numbering). • Turning "MN" and "MX" symbols on and off. The MN and MX symbols identify the locations of the minimum and maximum contour values. The MINM label on the /PLOPTS command enables you to turn these symbols on and off. • Producing 3-D isosurface, particle gradient, or gradient triad displays. Isosurfaces, particle clouds, and gradient triads are tools that can help you visualize the state of response within a 3-D solid body. By issuing the /CTYPE command (Utility Menu> PlotCtrls> Style> Contours> Contour Style), you can change your contour displays to one of these three styles of display. 14.3.4. Changing the Number of Contours By default, the ANSYS program displays nine contours. To decrease (but not increase) the number of contours, you can either issue the /CVAL command (Utility Menu> PlotCtrls> Style> Contours> Nonuniform Contours). To change (increase or decrease) the number of contours, you can issue the /CONTOUR command (Utility Menu> PlotCtrls> Style> Contours> Uniform Contours). However, one or more of the following factors can prevent ANSYS from displaying more than nine contours: • The device name. • Whether the display is directed to the screen or to a file. • The display mode (vector or raster). • The number of color planes. Any of these factors can override the number of contours you specify via /CONTOUR. You control these factors using either the /SHOW command (Utility Menu> PlotCtrls> Device Options). In any case, the maximum number of contours available is 128. The paragraphs below explain how device name, display mode, etc. limit the number of contours available to you: Driver The X11 driver (screen display) and raster mode The X11 driver (screen display) and raster mode Contour Display You can display a maximum of nine contours, no matter how many contours the /CONTOUR command specifies. You can display more than nine contours, but the number of contours displayed will be rounded down to the next lowest multiple of nine. For example, if you specify 20 contours, the program displays only 18 contours. In addition, if you specify more than nine contours, contour colors will not be unique (that is, you might have two or more adjacent contour lines with the same color). Release 13.0 - © SAS IP, Inc.
