How to check if the results accurate upon activating stabilization in step?
(OP)
I use a factor for stabilization in step for my simulation, How should I make sure It works?
What energy outputs should I compare?
What energy outputs should I compare?

I see some people talk this way:
Now just sum up ALL SD+ALLCD+ALLVD and divide it by ALLIE and establish the dissipation percentage.
Practically, damping dissipation shouldn't be more than 2% as it would affect the physical system. Choose the damping for which 1.Solution converges and 2.The dissipation % is a minimum
How do you say about that?
An should I also compare kinetic energy with something?

I definitely agree that this artificial damping should be as low as possible so that it won’t affect the solution too much. On the other hand it must be enough to enable convergence. However remember that you should always make sure that there are no errors in your simulation causing non-convergence as automatic stabilization may help complete the job but results would be incorrect anyway in this case.
