Model Sensors

Sensors help you detect events of interest in a simulation as well as respond to the event in various ways.

For example, you may define a sensor to detect the event at which the constraint force in a hinge exceeds a critical value. When this event occurs, you may deactivate the hinge to simulate failure of the joint and then restart the simulation

MotionSolve provides two types of sensor elements:
Defines both the event to be detected and the action to be taken when the event is detected.
Defines an expression to be evaluated when the event occurs. Thus, the element may store a flag that represents the state of the system at the time of the event, or it may compute a signal value at the event time.
