Mechanical simulation software The MathWorks
Simulink

SimMechanics™ extends Simscape™ with tools for modeling three-dimensional mechanical systems within the Simulink® environment. Instead of deriving and programming equations, you can use this multibody simulation tool to build a model composed of bodies, joints, constraints, and force elements that reflects the structure of the system. An automatically generated 3-D animation lets you visualize the system dynamics. You can import models complete with mass, inertia, constraint, and 3-D geometry from several CAD systems.
