Is it possible to simulate inelastic collision (where the two colliding part "stick" after collision) in motion study? 

I am able to simulate perfectly elastic collision by setting the restitution coefficient of solid contact to 1 

However, when i change the restitution coefficient to 0, the two part did not stick (my understanding is that if the coefficient of restitution is 0, the part should stick together after collision)

Am i missing something here?
