Coarse-grained models

Coarse-grained models are simplified representations of complex systems, like molecules or materials, that focus on their overall behavior rather than every tiny detail. By grouping atoms or components into larger units or "beads," these models reduce complexity, making simulations faster and more manageable. They are useful in studying large systems like biological cells or polymers, where detailed atomic-level models would be too computationally intensive. Essentially, coarse-grained models strike a balance between accuracy and efficiency, capturing essential features to understand system dynamics without getting bogged down in every minute detail.
