Scroll Wave Pinned to Double Torus

Numerical simulation of a scroll wave in an excitable, three-dimensional system. The rotating wave (golden areas) is pinned to an unexcitable, double-torus-shaped obstacle (blue). Rotation occurs around both obstacle holes. Notice that wave traverses the holes in different directions. This situation creates a two-armed scroll wave in the middle of the double torus and one-armed scrolls along the unbranched rings. This simulations is based on the Barkley model and describes the reaction-diffusion dynamics of one activator and one inhibitor species.
