Abstract
In this presentation we show that metadynamics, when used to simulate $CP^{N-1}$, allows to address efficiently of freezing of topological charge, to reconstruct the free energy of the topological charge $F(Q)$ and to compute the topological susceptibility as a function of the coupling and of the volume. We discuss possible extensions to QCD.
