Does chaos means long term numerical simulations useless?

  1. Dec 5, 2009 #1
    i am now reading a prl paper

    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

    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.

    and actually, it is almost impossible to make correct simulations
