Can i get the value of impact energy in Explicit Dynamics ?

      I need any kind of measurement that can be evaluated as a results after impact. Either the value of Impact Energy, minimum & maximum value of Absorption Energy, Velocity value before & after impact or anything that can be use as a results for impact energy.

      You can right-click on the solution andInsert>Deformation>Total VelocityorDirectional Velocity. You can scope it to the body as needed.
      I have given drop height as 500 mm, that means impact velocity will be 3131 mm/s. If you plot total velocity as described above you will get velocity after impact also.(shown in 2nd image)

      There are too many different values shown in the results. which one is the value of velocity after impact ? *p/s : my initial velocity is 35.357m/s so supposed to be maximum velocity is 35.357m/s as well right ? so which one is the minimum value to show the velocity after impact ? or should i take the average value in the table ? I'm looking forward for your consult, tq.

      If you have scoped it to a body that means it is a bunch of nodes and it would always pick a min, max and average them out. The scope can be all bodies, one body, one face, one edge or one vertex. If you scope one vertex there is a single value for max, min and average.
      Generally we consider average value.
