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.
