To be more precise, we could compute incrementally the work done by
the springs in the systems more than the elastic energy. Almost in the
same way as we get the dissipated energy due to friction (it is not
too difficult to make distinction between work and energy if we think
that work is defined as a variation of energy, hence we get it
incrementally). I just guess which one should be monitored, if the
work done or the energy..
We could compute incrementally. However, I don't see any advantage while
I see two drawbacks.
(1) It would take more time : incrementing MUST be done at each step, or
you miss some work done and all subsequent results will be missing this
part. OTOH, you can compute elastic energy only on demand (say, each N
iterations) with total equations.
(2) It would result in accumulating rounding errors, so better avoid it
IF possible.
For me, monitoring energy or work is almost the same. Like if you were
studying motion, you could monitor velocities or positions, they are
just different orders derivatives of the same function.
