Duffing Phase Model is a free and easy to use simulation that 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.
Duffing Phase Model displays the evolution of a group of oscillators with similar initial parameters on a phase space plot.
The evolution parameters can be changed via text boxes.
