Simulations of the melting transition of 2D clusters are presented. Equilibrium melting is obtained by increasing the kinetic temperature of the dust particles. Non-equilibrium melting occurs when an additional particle is placed in a layer below the cluster plane. The presence of the lower particle drives the transition by the onset of unstable oscillations. The mode spectra of the two melting processes allow detailed insight into the governing mechanisms.
