Residual velocity calculation

      Hello, I am simulating the glass penetration by bullet where I am interested in having the output data of the residual velocity of the bullet. The bullet is taken as the rigid body as at first when I tried outputing the surface velocity, it behaved anomaliously due to deformations. I am actually specifically interested in the normal velocity of the bullet that would be coupled with the center of the mass and not the surface. This is important as the bullet starts spinning after it exists the target, thus giving me the wrong values. Is it possible to achieve this without adding the script inside the explicit dynamic tool?

      Hello, are you using explicit dynamics as in the auto-dyne solver? You can handle this in Dyna easily and you can get the nodal velocity or the rigid body responses to get what you are looking for.
