The file size is 1.34 MB, Duffing Attractor Model, analyze the non-linear Duffing equation with this tool. The Ejs Duffing Attractor model computes the solutions to the non-linear Duffing equation, which reads, x'' + 2 x' - x (1 - x2) = f cos( t), where each prime denotes a time derivative. The simulation displays a three-dimensional plot of phase...
