I have one very simple question regarding ANSYS-AUTODYN and LS-DYNA. It seems that both can model impact loads.

My
questions is which can model low-velocity impacts and which can model
high-velocity impacts. I have some troubles modelling low-velocity
impacts in autodyn (changing the mass of the projectile does not affect
the pressure and the stresses on the target. Does this mean autodyn
only models high-velocity impacts)
