Domain walls in a 3d expanding universe

Formation of domain walls in a simulation of a scalar field with a symmetric double well potential, V=1/4*(\phi^2-1)^2. The universe expands and the box size is bigger than the hubble horizon, enabling the formation of domain walls.
Plotted here, are isosurfaces of the field at \phi=0 (green). \phi=1 (blue) and \phi=-1 (red)
