Fig. 3From: Cell structure formation in a two-dimensional density-based dislocation dynamics modelTime evolution of spatial patterns ρ(r,t) and κ(r,t) ; top: patterns growing from uncorrelated Gaussian noise (initial condition (i)), bottom: patterns growing from a single localized perturbation (initial condition (ii)); parameters: D=A=0.2,τext=1.1, these parameters are chosen to match experimental observations shown in Fig. 7Back to article page
