Solve Duffing equation fast and easy. Duffing Phase 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 the evolution of a group of oscillators with similar initial parameters on a phase space 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.
