Duffing Oscillator Model

The Duffing Oscillator model computes the solutions to the non-linear Duffing equation, which reads, x'' + 2γx' - x (1 - x 2 ) = f cos(ω t), where each prime, where each prime denotes a time derivative. The simulation displays the solution as well as the phase space and Poincare plots, and energy diagram. 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.
