A Voronoi diagram is created using Surface Evolver, from a random set of (N=1000) points to represent the grain structure. The boundary length is then minimised, subject to the constraint of constant area. The video shows the growth of a two-dimensional grain structure. |

A box containing some soap solution is used to simulate a grain structure. Rigorous agitation will produce an initial structure of many small bubbles (grains), whose evolution can be recorded. The soap film that separates bubbles has a surface energy, and the area of this will tend to be minimised.
