Phase-Field Modeling of Solidification

Over the past few years,the phase-field method has emerged a one of the most promising methods for the numerical modeling of complex solidification processes. Its principal numerical advantage is that it avoids the need for the tracking of a solid-liquid boundary. This minisymposium will focus on recent advances in phase-field methods as well as its applications to a diversity of solidification processes. These advances are made possible by the increased speed and memory capacity of computers and by new ways of deriving the thin-interface limit. The speakers will provide a concise overview of the current status of the phase-field method and its applications.
