Gathering information on molecular-scale crystallization events, particularly nucleation, requires a high degree of time and space resolution. This poses significant challenges for in situ experiments, often leading to only speculative interpretations of molecular mechanisms. In contrast, modelling techniques based on MD simulations inherently provide insight into the time evolution of systems with atomistic detail, making them a powerful tool for understanding complex processes such as nucleation. However, the small system sizes and limited simulations times available to the simulator mean that advanced simulation methods must often be used to simulate nucleation.
