Summary

Description
English: Image 3 (state at t=100) of a sequence showing a Turing bifurcation from a noisy ground state to a hexagonal state in a two-component reaction-diffusion system of Fitzhugh-Nagumo type, generated by Dr. H. U. Bödeker.

The system reads:

with τ = 0.1, du2 = 0.00028, dv2 = 0.005, κ = - 0.05

and was solved using a finite-element algorithm.
