Sample stationary solution of Gierer-Meinhardt system with two morphogens in two spatial dimensions. Panels correspond to (left) inverted spots with q = -2 and r = 4.5, (center) stripes with q = 0 and r = 1, and (right) spots with q = 2 and r = 4.5. All other model/simulation parameters are indicated in the text. Simulations were run until a numerical steady state was reached (maximum difference in any lattice point less than 1e-16, the machine epsilon).
