Duffing Attractor Model

The Duffing Attractor Model computes the solutions to the non-linear Duffing equation, which reads, x'' + 2γ x' - x (1 - x 2 ) = f cos(ω t), where each prime denotes a time derivative. The simulation displays a three-dimensional plot of phase space versus angle and three Poincare plots separated by angles of 2/3. The evolution parameters can be changed via textboxes. You can modify this simulation if you have Ejs installed by right-clicking within the plot and selecting "Open Ejs Model" from the pop-up menu item.
