This is an on-lattice application which evolves a Q-state Potts model in combination with a phase field Cahn-Hilliard model. It can be used to efficiently simulate grain growth in a two-phase system controlled by diffusion. For a full description of the model, see the paper by Homer et al..

See the examples/potts_pfm directory for an example script using this command. See the Pictures web page for images of simulations performed with this command.

The following additional commands are defined by this application:

temperature set Monte Carlo temperature

Restrictions: none

The keyword defaults are reset_phasefield = no, print_connectivity = no, initialize_values = no, enforce_concentration_limits = no.
