| Abstract Scope |
The Sharp Phase Field Method (S-PFM) is a phase-field method in which interfaces are resolved with only one grid point with no pining on the grid and accurate rotational invariance, allowing to reduce the computational resources by almost three order of magnitudes [1].
SPFM was initially formulated for microstructures that can be described by a single-phase field. We present here its extension to a generic multiphase field formulation that allows microstructures containing an arbitrary number of phases to be considered and that allows the energy and mobility of any two-phase interface to be chosen independently of all the others, while preserving the properties of the initial method.
