Crystallization phenomena are of first interest in several industrial applications (polymer forming processes, metallurgy, phase change flow, energy storage...). A classical way to model the crystallization evolution is using the Nakamura kinetics law. In this paper, a novel physics interface is developed using the Physics Builder of COMSOL Multiphysics® , which accounts for the resolution of this Nakamura kinetics. The new physics can be used in any COMSOL® model. An example of composite forming simulation, which includes the coupling with a heat transfer node is presented. The new physics interface is efficient at automatically handling couplings and also calls for physical material properties with consistent units. Thus, using this custom physics interface will prevent mistakes when developing new models.
