Gray-Scott Reaction-Diffusion

About the simulation

This Java applet simulates two chemical agents bound by the Gray-Scott reaction. Stepwise integration is used, and diffusion is modeled in the simplest way possible.

Gray-Scott equations

More functionality and information will be added here later.

The 2D version of the applet is better-developed (and prettier). Also, there is more information about the physical system modeled here.

Clicking in the window sets local values.

  • Left-button: U=0.5, V=0.25
  • Right button: U=1, V=0
