Update the block diagram to assemble the model and visualize its initial
configuration. The visualization opens in Mechanics Explorer. Simulate the
model to play an interactive animation. Be sure to pick a solver suited for
physical models, such as
Ode15s, and to specify a
maximum time step small enough to capture the fastest meaningful change
expected during simulation.
Open Camera Manager to add a moving,
dynamic camera with which to capture the animation. Dynamic cameras can be
of two types: keyframed or tracking. Keyframed cameras move between view
points created interactively in Mechanics Explorer. Tracking cameras attach
to and aim at frames in the model. Use Video Creator or the
smwritevideo function to record
an animation in a video format.

frame variables and assign both joint and frame variables as targets,
guesses, and outputs for analysis.

Workflow steps for updating and simulating a Simscape™ Multibody™ model.
Visualization is not only a central part of a multibody simulation, it is an essential tool in modeling bodies and verifying their shapes, sizes, frame placements, and colors. Here is an overview of the visualization utilities available in the Simscape Multibody environment and the roles they play in your modeling workflow.
Set the model configuration parameters to ensure that Mechanics Explorer opens automatically on model update or simulation.
Select a standard view, set the up-axis convention, and use mouse shortcuts to rotate, roll, pan, or zoom a model.
Use Mechanics Explorer frame highlights and Graphic blocks to visualize frames.
Visualization filtering as a means to selectively show and hide solids, bodies, and multibody subsystems in Mechanics Explorer.
Use selective model visualization to show only those model components that are relevant to you.
Use Mechanics Explorer to go to the block corresponding to a tree view pane node.
Use Camera Manager to create or edit a model visualization camera with a moving viewpoint.
