Molecular simulation is a computational technique used to study the structure, properties and behaviour of atoms and molecules. It allows researchers to investigate complex physical and chemical systems that may be difficult, expensive or impractical to study experimentally.
Molecular dynamics is a type of molecular simulation that models the movement and interactions of atoms and molecules over time. By calculating the forces acting on particles, these simulations provide insights into molecular behaviour, structural changes, thermodynamic properties and interactions between different substances.
Molecular dynamics software can simulate proteins, liquids, polymers, membranes and solid materials. These tools typically support the construction of molecular models, execution of simulations and analysis of results. Many take advantage of parallel processing and GPU acceleration to handle computationally demanding simulations.
The software is useful for computational chemists, molecular biologists, biophysicists, materials scientists and pharmaceutical researchers. It also provides valuable educational resources for students studying molecular modelling and computational science.
