Molecular dynamics (MD) is a computational simulation method used to analyze the physical movements of atoms and molecules. It involves numerically integrating Newton's equations of motion for a system of interacting particles, typically based on interatomic potentials, over a period of time. This allows scientists to predict the time evolution of a molecular system, exploring its structural and dynamic properties, and understand its behavior at the atomic level. MD simulations are employed across a wide array of scientific disciplines, including materials science, chemistry, and biophysics, to investigate diverse phenomena such as protein folding, drug discovery, and materials properties.
