AutoCAD Inventor Simulation Suite 2011 Includes all the core functionality of AutoCAD Inventor Suite 2011 plus motion simulation and stress analysis. This makes it easier to predict how the design will work under real-world conditions before the product is built.

Simulation capabilities in Inventor can help you:

Optimize the strength and weight of your designs to minimize material usage.
Set up tests you can feel confident about, based on real-world constraints.
Check designs for high stress concentrations and modify part geometry to meet safety factors.
Size motors and actuators to reduce energy consumption and costs.
Identify and reduce unwanted vibrations to improve product quality.
Improve product performance by investigating dynamic behavior of mechanisms.
Design cams and grooved paths by specifying the motion of followers.
Balance rotating components to reduce internal stresses.
