OpenPhase is an open-source C++ software project started in 2008 at the Interdisciplinary Centre for Advanced Materials Simulation, Ruhr-Universität Bochum, Germany. OpenPhase is dedicated to investigating microstructure evolution in materials undergoing first-order phase transformations, capillarity-driven coarsening processes, or a combination of both. Also you may embed the simulation into a macroscopic process simulation which determine boundary conditions on the micro domain, heat fluxed, mechanical loading or others.
