We study the creation of disoriented chiral condensates with some initial boundary conditions that may be expected in relativistic heavy ion collisions. The equations of motion in the linear [sigma] model are solved numerically with and without a Lorentz-boost invariance. We suggest that a distinct cluster structure of coherent pion production in the rapidity distribution may emerge due to a quench and may be observed in experiments.
