Displaying alternate FEM representations

Use the Graphical Representation options in the FE Model Component Representation dialog box to control how the software displays the alternate representation of the component FEM or assembly FEM model when you create a mode set or FRF set.

Graphical Representation option	Description	Example
Approximation of base FEM	Displays a transparent, non-selectable approximation of the nodes and elements of the base FEM file.
Super Element Symbol	Displays a generic, symbolic representation of the representation as a spider element
None	The software does not display any graphical representation of the alternate representation.

Mode and FRF set display examples

This example model shows an assembly FEM that is attached to a beam structure.

An alternate representation of the component FEM is shown in the table, showing how the choice of options affects the display.
