Simulations of Eq. (41) with kinetics given by (50) using parameters FHN1. We plot the distribution of u on a the domain before growth, b the final static domain, and grow the domain using staged growth over the timescale $T_g=10T^{\ast }$ in c–e where c is at $T^{\ast }+T_g$, d is at $T^{\ast }+2T_g$, e is the final stationary pattern in the staged growth case, and f is the isotropic growth case over the same growth period as in each staged direction (Color figure online)
