Information

Static Force

Component that can add forces in all three directions, x, y and z. The forces can be individually controlled in time interval and amplitude, defined by ramp signals. To stop applying a force, the step signal in the desired direction is activated, multiplying the force amplitude by zero.

Type: Real[3]

Description: Amplitude of the force applied in x,y,z direction

start

Value: {0, 0, 0}

Type: Real[3]

Description: Time when to start applying a force in x,y,z direction

duration

Value: {0, 0, 0}
