AvarmanPCM

AvarmanPCM is a computational modeling technique used in materials science and engineering. It is a multi-scale approach that combines different simulation methods to capture phenomena across various length and time scales. The core idea behind AvarmanPCM is to leverage the strengths of each individual method to overcome the limitations of using a single technique for complex material systems.

The "PCM" in AvarmanPCM stands for "Phase-Field Crystal Method." This method is a continuum theory that describes the atomic structure of crystalline solids. It allows for simulations of crystal formation, growth, and defect dynamics at atomistic resolution without explicitly tracking individual atoms. This is achieved by treating the atomic density as a continuous field.

AvarmanPCM typically integrates the Phase-Field Crystal method with other simulation techniques. For instance, it might couple atomistic simulations, such as Molecular Dynamics, with Phase-Field Crystal simulations. This allows for the study of phenomena that span from atomic interactions to macroscopic material behavior. By doing so, AvarmanPCM can investigate processes like phase transformations, crack propagation, and the evolution of microstructures under various conditions. The goal is to provide a more comprehensive understanding of material properties and performance than can be achieved with single-scale methods.
