# Multiphase Interface Planarization

Tóth *et al.* (*Physical Review B* **92** (2015) 184105) reviewed competing

multiphase-field models for thermodynamic consistency and kinetic stability of planar

interfaces at equilibrium. This repository contains multiphase-field models intended

for evolution of multiphase systems with pairwise-asymmetric interfacial

properties. The example codes demonstrate equilibration of the planar binary

interface produced upon collapse of a ternary system with one phase encapsulated

within a circular domain (grain). The models are based on the excellent write-up in

Ref. 1, with specific details in further references. Numerical simulations for three

of the most popular/significant/relevant models are implemented in the subdirectories

using [MMSP](https://github.com/mesoscale/mmsp).
