Rapid multiphase-field model development using a modular free energy based approach with automatic differentiation in MOOSE/MARMOT

We present a novel phase-field model development capability in the open source MOOSE finite element framework. This facility is based on the “modular free energy” approach in which the phase-field equations are implemented in a general form that is logically separated from model-specific data such as the thermodynamic free energy density and mobility functions. Free energy terms contributing to a phase-field model are abstracted into...
