Having carried out programs for simulating physical systems, I note that snapshoot seems to completely ignore the content of this program, often very complex and essential to know its exact limits and risks of serious errors, by describing only dreams with the simulation :
1)
physical models used, assumptions behind, in general
physical equations differential or partial derivatives (much more complex)
conserving energy!
2)
mathematical methods, which can
cause a surunity of energy, on equations, which at the beginning, conserve energy perfectly, as I already explained on econology for a similar post with simulation of a simple coupled oscillator, a total aberration !!
Even, it is difficult to conserve energy in a long-term dynamic simulation, because we take a finite step of iteration on the usual iteration equations, and in general they do not conserve energy without the slightest error and therefore
small accumulated errors most often end up with false results, with not enough or too much energy (false on the energy in the simulation then, with misleading excess energy in the simulation), on starting equations which physically conserve energy perfectly.
Simulations are a whole mathematical area to be aware of, with great care, which if ignored, leads to beautiful errors.
So the simulation risks proving nothing, unless we check that its discretized equations conserve energy, and then the snapshoot system will remain at constant energy, on its momentum, if there is no dissipation or friction, put in the simulation software, and will lose its energy gradually with friction, to stop with certainty.
Simulation, if the software is well done, and well used, will never give perpetual motion.
Only real experiences can prove it, contradicting all of our current knowledge, but we are waiting for clear proof verifiable by all of us.
An almost inexhaustible form of energy is nuclear energy, discovered with radium which heated spontaneously, unceasingly, which contradicted all knowledge in 1900, and which was clarified by discovering its source of radioactive energy stored for 5 billion years !!
No simulation at the time could have proved the reality of nuclear power.
A simulation only uses what we already know and we discover nothing more, in particular, it is impossible not to conserve energy in a valid simulation which does not describe imaginary dreams as a result of errors.
