Demos/Examples
Here are some demo programs created with EJS, just to give you a flavor of the type of simulations you can create with it.

Mathematics
- Arenstorf orbits: Arenstorf orbits are closed trajectories of the restricted three-body problem. JAR. XML.
- Lorenz attractor: The three-dimensional Lorenz attractor shows the sensibility of simple non-linear ordinary differential equations to initial conditions. JAR. XML.
- Planet choreographies: Curious planar trajectories of n-bodies under mutual gravitational attraction. JAR. XML.
- Vibrating string: We solve the one dimensional wave equation using an explicit difference method to display a vibrating string. JAR. XML.
- Poisson equation: We solve Poisson partial differential equation in the plane, using the relaxation method, to display an electrostatic field. JAR. XML.
- Heat equation: We solve the one dimensional Heat partial differential equation, using the method of lines, to display the flow of heat in a thing metal bar. JAR. XML.

- The EJS distribution includes a lot of additional examples.
- If an Internet connection is available, from the EJS’ interface you can connect to on-line digital libraries with dozens (if not hundreds) of examples.
