[FAQ]

Although the time history of the directional acceleration at the specified nodal locations is available from results trackers inserted under Solution Information, average directional acceleration per body is not directly available in Explicit Dynamics system. However, user can insert Body Results Trackers under Solution Information to output the time history of the directional external or contact force on the specified body or bodies. This force is the sum of the total external or contact forces acted on the specified body(ies). Then user can divide the directional force by the body mass that is available under details of the geometry to get the averaged directional acceleration.
