Abstract
Molecular-dynamics studies of a model belonging to the Ising universality class, covering the order-disorder and displacive regime of distortive phase transitions, are reviewed. The results offer a unified picture of these transitions in terms of clusters and their dynamics. As a consequence, the soft-phonon picture sufficiently close to Tc is expected to fail.Keywords
