i am now reading a prl paper(adsbygoogle = window.adsbygoogle || []).push({});

the authors used numerical simulations to study a nonlinear system

in some parameters, the authors state that system enters into chaos

My numerical simulations are the same as that of the authors in the regular regime

but in the chaos regime, my simulations are quite different from theirs.

I guess in the chaos regime, numerical simulations are useless

Due to numerical errors, the simulation results in the long term are not valid at all.
