Using energy results

Hi all,
In you stress, strain and contact analysis simultations, I am trying to learn more about how the experts use energy results to confirm the validity of the results.
Thanks

Both, I would really like to learn more about this. Thanks.
RE: Using energy results
In a quasi-static analysis the value of the kinetic energy (ALLKE) should not exceed a small fraction of the value of the strain energy (ALLIE).
It is a good practice to output the constraint penalty work (ALLCW) and the contact penalty work (ALLPW) in analyses involving constraints (such as ties and fasteners) and contact. The value of these energies should be close to zero.
