The Duffing Measure model computes the solutions to the non-linear Duffing equation, which reads, x'' + 2γx' - x (1 - x2) = f cos(ω t), where each prime denotes a time derivative. The simulation displays the evolution of a group of oscillators with similar initial parameters on a Poincare plot and the evolution of the oscillator with the central initial parameter displayed on a separate Poincare plot. 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.
