Provides the highest accuracy by including quantum-mechanical interactions but is limited to small systems (hundreds of atoms) due to extreme computational costs.
Modeling and simulation of amorphous materials focus on understanding atomic-level structures that lack long-range order but possess significant short-range order. Unlike crystals, these materials have no unit cell or Bragg peaks, requiring large-scale simulations to capture their structural randomness and property-shaping local environments.

The most common technique involves heating a crystalline or random initial structure above its melting point and rapidly cooling it. This "freezes" atoms into a disordered state. Modeling and Simulation of Amorphous Materials ...
Updates atomic positions step-by-step by calculating interatomic forces. It is widely used to study time-dependent phenomena like diffusion and glass transitions. Modeling and Simulation of Amorphous Materials ...
