      Few members were facing the same issue yesterday, which got fixed in some time. Could you try again and let us know if you are still unable to login?
      To give you a quick answer I'll reiterate Sandeep's comment:
      "In an ideal situation, All of the kinetic energy of the hammer should be transferred to the potential energy. Please look at the internal energy.
      Internal energy is nothing but energy stored in bodies due to deformation. This includes both Plastic Work (material model) and Hourglass Energies (reduced order elements).
      Useful section from the Help: Section 1 and Section 2 "
      Regards Ishan.
