The simulation temperature in the Monte Carlo Potts model of grain growth is not correlated to any real experimental temperature and has been introduced into the simulation purely to activate thermal fluctuations that roughen the grain boundaries and prevent an unphysical lattice effect-namely the pinning of grain boundaries and their junctions to the underlying lattice. In the present paper the use of the simulation temperature is reviewed and a new procedure is proposed to find for a given set of lattice parameters one adequate simulation temperature that yields curvature driven grain growth kinetics exactly as predicted theoretically.
