Very cool! Were the evenly spaced nine structures at 0:30 a result of non-random starting positions? Was it simply emergent?

- klarh 11y agoIf you look carefully, everything for the whole video is replicated 9 times. These simulations typically use periodic boundary conditions: if something goes out the left side, it is put in at the right side, and so forth. This significantly decreases boundary effects that would arise from putting interfaces into the simulation. Only one of the 9 cells is really being simulated, but they replicate it once in each direction for visualization so you can see what is happening through the boundary conditions.
