Changing the Specifications for Your Geometry Displays In addition to the features listed below, also see Getting Started with Graphics (p. 217) for general graphics specifications that apply to any type of display, including geometry displays. 13.2.1. Changing the Style of Your Display The following sections describe a number of ways to change the way your models are displayed. 13.2.1.1. Displaying Line and Shell Elements as Solids If your model consists of line elements (such as beams and pipes) or shell elements, you can use the following to display many of them as solids: Command(s): /ESHAPE GUI: Utility Menu> PlotCrls> Style> Size and Shape The ANSYS program uses a rectangular cross section for beams and shells, and uses circular cross sections for pipes. The element real constants are used to proportion the cross section. You can also use the /ESHAPE command to show the orientation of reinforcing (rebar) in SOLID65 elements (see Figure 13.1 (p. 241)). For the rebar to be visible, you must enable vector mode using the /DEVICE command (Utility Menu> PlotCtrls> Device Options). You must also activate a basic plot type using the /TYPE command (Utility Menu> PlotCtrls> Style> Hidden-Line Options). To view the rebar, issue these commands in the following order: /ESHAPE,1 /TYPE,,BASIC /DEVICE,VECTOR.ON EPLOT 240 Release 13.0 - © SAS IP, Inc.

Figure 13.1 Element Plot of SOLID65 Concrete Elements 13.2.1.2. Displaying Only the Edges of an Object While working with displays, you might want to see only the edges of an object; that is, you might want to remove element outlines from the interior of the object. To see only the edges of non-contour displays (EPLOT), issue /EDGE, ,1 (Utility Menu> PlotCtrls> Style> Edge Options). On contour displays (PLESOL, PLETAB, PLNSOL, PLTRAC), edges are displayed by default (/EDGE, ,0). 13.2.1.3. Displaying the Interior Element Edges of an Object While working with displays, you might prefer to see the interior element edges, or detail, of an object. If you are working with non-contour displays (EPLOT), the interior element edges are displayed by default (/EDGE, ,0). To see the interior element edges of contour displays (PLESOL, PLETAB, PLNSOL, PLTRAC), issue /EDGE, ,1. An edge, as used in the above context, is the common line between adjacent faces that are not coplanar. The ANGLE field on the /EDGE command allows you to specify the "degree of coplanarity" at which an edge should be displayed. That is, if ANGLE = 45° (which is the default value), an edge is displayed only if the two adjacent faces deviate from coplanarity by more than 45°. If ANGLE = 0°, even the slightest deviation from coplanarity causes the edge to be displayed. The default value of 45° is particularly helpful in displaying a cylindrical shell model as a smooth cylinder rather than as a "faceted" cylinder. 13.2.1.4. Using Dashed Element Outlines You can switch the style of element outlines from solid line to dashed line by using the /GLINE command (Utility Menu> PlotCtrls> Style> Edge Options). This command allows you to remove element outlines entirely. 13.2.1.5. Shrinking Entities for Clarity The /SHRINK command (Utility Menu> PlotCtrls> Style> Size and Shape) shrinks displayed elements, lines, areas, and volumes by a specified percentage so that adjacent entities are separated for clarity. ANSYS ignores a request to shrink the display when the edge option is active. 13.2.1.6. Changing the Display Aspect Ratio You can artificially distort your display's geometry in a particular direction with the /RATIO command (Utility Menu> PlotCtrls> Style> Size and Shape). This can be useful for displaying details within a long, skinny object more clearly. Release 13.0 - © SAS IP, Inc.
