Hello! A follow-up question... what is the difference between the energy values provided in *glstat and *matsum?

I checked the kinetic energy vs internal energy in *glstat (which I guess would be total energy sum) and the kinetic energy is indeed less than the internal energy, but in *matsum this is not the case.

I am using a lot of discrete elements to represent ligament connections (see picture for reference) and I guess this is why I get total energy higher than the kinetic one, but all the remaining parts containing solids or shells have kinetic energy higher than internal energy in *matsum... I suppose this means that I need to simulate a longer time? Or is the *glstat total energy enough for confirming quasi-static behavior?
