This Tips & Trick shows how to display polygon bodies together with results in the post-processor.  It also shows how to activate Mirror Display.


We will explore these functionalities on a Battle Droid model, on which a modal analysis was performed. The droid is meshed using solid elements, except for the torso which is idealized using beam elements.



In the Simulation Navigator, double-click the Solution’s Results node.

Figure 1. Simulation Navigator


In the Post-Processing Navigator, plot any result and edit the post view to your liking.  In this case we have plotted the displacements for Mode #10.

Now, change the Layer Settings.

  • Menu -> Format -> Layer Visible in View…
  • Click Reset to Global

Figure 3. Resetting Visible Layer


The following dialog is displayed.  To view all layers, click OK.

Now, from the Simulation Navigator, it is possible to display polygon bodies, meshes, boundary conditions and so on.  

We will hide the Droid’s torso mesh and replace it with the polygon body representation.

  • In the Post Processing Navigator, under Post View1, Expand the 1D Elements
  • Un-check the mesh to be hidden.

  • In the Simulation Navigator, under the fem part, expand until the polygon bodies are exposed
  • Activate the polygon body to be displayed.

We will now activate and set the Mirror Display to give the appearance of another droid.

  • View Tab (ribbon) -> Visibility Group -> More

Use the handles to move and orient the so that the Mirror Plane is located properly.


In the next figure, the Normal vector (in green) is the reflection plane’s normal.  The origin of the coordinate system is on the reflection plane.

  •  View Tab -> Visibility Group -> More

Figure 8. Mirror Display Active


  • Results Tab (ribbon) -> Animation Group ->

  • Set the animation as shown below.


Figure 9. Animate with Mirror Display Active


 The animation can be viewed with the following animated .gif file.

It shall be noted that Mirror Display is available outside of the post-processor too.
