• GSTIFF /I3 � � � � � � �� � � � � � �If you notice that energy is dissipated during contact events, note the following:Impact method - A three-dimensional contact with zero damping can exhibit some

dissipation of energy during the impact. The dissipation is due to the numericsof the integration algorithm. To reduce the dissipation, reduce the time step or tighten (decrease) the error tolerance. __ ADAMS HELP
