Originally shared by Cornus AmmonisAn interesting, partially accidental discovery.

A Fitzhugh-Nagumo system, using Ising regime parameters, coupled to a fluid simulation. The anisotropy of the Laplacian kernel is controlled by the flow vector at each point. In other words, the rate of diffusion in each direction is controlled by fluid flow. This is conceptually similar to the reaction-diffusion-advection scheme described in this paper by Theodore Kim: http://gamma.cs.unc.edu/SARD/stable_ard_kim_lin.pdf The rotation is caused by flipping the X and Y coordinates for fluid flow in the Laplacian kernel.
