Hello,

Try to plot hourglass energy on top of all the other energies. Is hourglass energy high compared with internal energy? Does hourglass energy account for the energy “generated” in the model and contribute to the increase in total energy?

Also, does it make sense that gravity adds this much energy to the total energy? Do you have a way to calculate it by hand? Could you run the model without gravity and see the effect on total energy? Are there other loads or prescribed motion in the model that you are forgetting or neglecting that could do external work?

Let me know how it goes.
