A Markov process is constructed to numerically study the phase separation inthe 6-vertex model with domain wall boundary conditions. It is a random walk onthe graph where vertices are states and edges are elementary moves. Itconverges to the Gibbs measure of the 6-vertex model. Our results show clearlythat a droplet of "c" vertices is created when Boltzamnn weights are in theantisegnetoelectric region. The droplet is a diamond-like shaped curve withfour cusps.
