The Mechanics Explorer visualization utility opens by default whenever you update or simulate a Simscape™ Multibody™ model. Each model that you update or simulate adds a new tab to Mechanics Explorer. If Mechanics Explorer does not open, ensure that model visualization is turned on:
In the Modeling tab, click Model Settings.
Expand the Simscape Multibody node and select Explorer.
Ensure the Open Mechanics Explorer on model update or simulation check box is selected.
