[edit] Summary

Rotating spiral (numerical calculation) in a two-component reaction-diffusion system of Fitzhugh-Nagumo type, produced by Dr. H. U. Bödeker.

The system reads

$\begin{array}{rl} \partial_t u &= d_u^2 \Delta u + \lambda u -u^3 - \sigma v + \kappa,\\ \tau \partial_t v &= d_v^2 \Delta v + u - v \end{array}$

with λ = 4.67, τ = 4.0, d_u² = 0.0015, d_v² = 0.01, κ = -1.126, σ = -3.33, no-flux boundary conditions have been used.

A finite-element algorithm was used in the calculation.
