The Ejs Duffing Baker's Map 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 N^{2} Poincare plots each separated by the same phase angle. 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.

Ejs Duffing Baker's Map model was created using the Easy Java Simulations (Ejs) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_ehu_chaos_Duffing_Baker.jar file will run the program if Java is installed. Ejs is a part of the Open Source Physics Project and is designed to make it easier to access, modify, and generate computer models. Additional Ejs models for non-linear dynamics and chaos are available. They can be found by searching ComPADRE for Open Source Physics, OSP, or Ejs.
