Results Data
Results data can be post-processed using both HyperMesh and HyperView.
Developer
The Developer ribbon contains tools for automation and customization.
Plot Data
HyperGraph is a data analysis and plotting tool with interfaces to many file formats.

Ground

Use the Ground tool to change a rigid body or a rigid group to a grounded state.

To change a rigid body or a rigid group to a grounded state:

From the Geometry ribbon, click the Ground icon.
Select bodies that are to be grounded. The grounded body will be highlighted in red.
The body icon in the browser changes to .
To un-ground, click again on the body.

Comments

A default Ground Body exists in the model whose grounded state cannot be changed.
A grounded body/rigid group will not move during simulation.
Any connections and markers on the grounded body are moved to the Ground Body.
