Phase Field Module

Phase field results produced using the MOOSE Phase Field Module

The MOOSE phase field module is a library for simplifying the implementation of simulation tools that employ the phase field model. Multiphysics capability that includes mechanics and heat conduction can be obtained by employing the tensor mechanics and heat conduction modules. More information about this module is found below:

Multiple Phase Models

MOOSE provides capabilities that enable the easy development of multiphase field model. A free energy expression has to be provided for each individual phase. Different systems exist to combine those _phase free energies_ into a _global free energy_.

  • Two-phase Models: Two phases, one phase order parameter

  • Kim-Kim-Suzuki Model: per-phase concentrations, two phases

  • Multiphase Models: phases, phase order parameters

  • Grand Potential Model: solving a Legendre transform of the phase field equations, where the independent variable is the chemical potential
