  Is there a way to give an ojet a kinectic energy instead of a velocity for an impact test. I'm looking to see the deformation of a hammer strike on an object to see if I need to reinforce it. The problem right now is that the hammer just keeps going to the same velocity ( not really a problem, it's the feature of the velocity) after the impact. I'm looking for an energy that will disipate as the deformation occurs.

  You can define an initial velocity:

  You need to use Initial Velocity under Initial Conditions to simulate the impact event.
  You should not use Velocity Boundary Condition to simulate the impact, because this will enforce the impactor moving in the constant velocity. However, in actual impact event, the velocity of the impactor is not a constant. Its magnitude will be reduced or its direction can be changed after the impact.
