Table C–8 presents the special graphical symbols used by the Visualization module. These special symbols appear when you produce an undeformed, deformed, contour, or symbol plot of a model containing any of these components. For information on customizing the color and size of these symbols, see “Coloring all geometry in the Visualization module,” Section 51.4, and “Controlling the display of model entities,” Section 36.10, respectively.

Table C–8 Special graphical symbols used by the Visualization module.

	Two-node dashpot elements
	The Visualization module displays two-node dashpot elements using the symbol shown. You can choose to display a straight line in place of this symbol by selecting Extra coarse refinement for all curved edges and faces in your model. For more information, see “Refining curved edges and faces,” Section 36.11.3.
	Two-node spring elements
	The Visualization module displays two-node spring elements using the symbol shown. You can customize the appearance of the curves in this symbol using the options for refining curved edges and faces. The Visualization module displays a two-node spring element as a straight line when you select Extra coarse refinement for all curved edges and faces in your model. For more information, see “Refining curved edges and faces,” Section 36.11.3.
	Reference nodes
	The Visualization module displays the reference node for a rigid surface as a cross. You cannot customize the shape of this symbol.
	Tracer particles
	The Visualization module displays a tracer particle as a cross within a square. You cannot customize the shape of this symbol.

In addition to the special symbols the Visualization module uses to display the model components listed above, you can choose to display symbols representing results, model entities (boundary conditions, coupling constraints, connectors, coordinate systems, and point elements), and nodal locations.
