energy conservatin in abaqus

[elahe337]

hello everyone
I am modeling an impact problem via Abaqus. and my model consists of an impactor and a solid ball.
The impactor impacts the ball through three different forces. and I extracted energy plots for all of these forces but I think they are not true because internal energy and kinetic energy didn't show an ending at the end of the plots.
does anyone know if these plots are true or not and what should I do to have a better plot?

[FEA way]

Make sure that the plot shows the whole analysis time (X axis is not cut). Possibly, generate the plot in Abaqus/Viewer. If still in doubt, compare it with plots in research papers discussing impact problems.

can you please tell me how should i plot the curves in Abaqus viewer? is it another software?

 

[FEA way]

It comes together with Abaqus/CAE - as a Visualization module or separately launched Abaqus/Viewer.
