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.
Two graphical user interfaces (GUIs) are available in Altair HyperWorks to build MotionSolve models: MotionView and HyperMesh.
Bodies are the only modeling elements that explicitly capture mass and inertia effects.
Constraints arise when the motion of a body is restricted by connections to other bodies.
The term force generically refers to both applied forces and applied moments.
MotionSolve provides a very sophisticated contact modeling capability that can handle complex contact scenarios between rigid bodies.
Sensors help you detect events of interest in a simulation as well as respond to the event in various ways.
This manual provides a detailed list and usage information regarding command statements, model statements, functions and the Subroutine Interface available in MotionSolve.
