How to simulate a free end boundary condition for a rod while the other end has a forcing?

Hi ,

 

I am doing a transient direct analysis of a 1D rod in optistruct .  On one end of the rod there is an axial sinusoidal displacement input. The other end is free. I want to look at the transient solution to this problem. 

i.e I want to see the travel of the first wave of deformation from the forced end to the free end. How can I set up this kind of boundary condition?

 

regards,

Vachan
