Ok. For this problem, I would simply block DOF's and assign constant 
velocities (i.e. impose displacement, not just initial velocity). Of 
course, the contact law must give correct results whatever the boundary 
conditions. So, there is nothing wrong in applying a force, the only 
problem is it gives less predictable results (since it is dynamic).
