Regarding unit of motion

Hi, I am using motionview to analyse my motorcycle's chassis while going on a road bump. I converted the chassis into a flex-body, and created a jack for the front wheel. I constrained the jack by a translational joint and also included the Bistop function. Under displacement I gave an expression, 50*sin(2*PI*TIME). My simulation ran without any error however, my travel was large. I wanted a 50mm travel but I'm not sure about the unit of this simulation. Could anyone please help me clarify this

    Hello,

    The MotionView units can be seen under model DataSets or Misc Units.

    to get a 50 mm total travel with that sine function, you need to divide 50/2.  Amplitude of the sine function is not the peak to peak amplitude, it's half.
