Abstract
We consider the metastable behavior of a superposition of a ferromagnetic spin system with a Glauber dynamics and stirring dynamics. Starting from configuration −1, minus spins at all lattice sites in a fixed volume under periodic boundary conditions, the process stays close to this configuration for an unpredictable time until the formation of a droplet, of spins +1, with a certain critical size and decays to configuration +1 in a relatively short time. We observe that the size of the droplet depends on the rate of exclusion.
