**Model Mechanical Systems**

A mechanical system can be thought of as being composed of a set of basic mechanical entities that interact with each other by exchanging energy or information in well-defined ways. For example, a simple pendulum system is composed of a rigid body connected to the ground by a revolute joint. MotionSolve provides physics-based, mathematical models of such entities and ways to assemble them into realistic models of complex mechanical systems. It then lets you simulate your models to gain insight into their behavior.**Graphical User Interfaces - MotionView and HyperMesh**

Two graphical user interfaces (GUIs) are available in HyperWorks to build MotionSolve models: MotionView and HyperMesh.**Model Bodies**

Bodies are the only modeling elements that explicitly capture mass and inertia effects.**Model Constraints**

Constraints arise when the motion of a body is restricted by connections to other bodies.**Model Forces**

The term force generically refers to both applied forces and applied moments.**Model Contacts**

MotionSolve provides a very sophisticated contact modeling capability that can handle complex contact scenarios between rigid bodies.**Discrete Element Simulation in MotionSolve**

A Discrete Element Method (DEM) is a numerical method that computes the motion and effect of a large number of small particles.**Model Sensors**

Sensors help you detect events of interest in a simulation as well as respond to the event in various ways.**Model Feedback Control Systems**
