Molecular dynamics (MD) is a computer simulation method for analyzing the physical movements of atoms and molecules. The atoms and molecules are allowed to interact for a fixed period of time, giving a view of the dynamic "evolution" of the system. In the most common version, the trajectories of atoms … See more MD was originally developed in the early 1950s, following the earlier successes with Monte Carlo simulations, which themselves date back to the eighteenth century, in the Buffon's needle problem for example, but was … See more The design of a molecular dynamics simulation should account for the available computational power. Simulation size (n = number of particles), timestep, and total time duration must be selected so that the calculation can finish within a reasonable time … See more In many simulations of a solute-solvent system the main focus is on the behavior of the solute with little interest of the solvent behavior particularly in those solvent molecules residing in regions far from the solute molecule. Solvents may influence the … See more Steered molecular dynamics (SMD) simulations, or force probe simulations, apply forces to a protein in order to manipulate its … See more First used in theoretical physics, the MD method gained popularity in materials science soon afterward, and since the 1970s is also common in biochemistry and biophysics. … See more A molecular dynamics simulation requires the definition of a potential function, or a description of the terms by which the particles in the simulation will interact. In chemistry and biology this is usually referred to as a force field and in materials physics as an See more A long range interaction is an interaction in which the spatial interaction falls off no faster than $${\displaystyle r^{-d}}$$ where $${\displaystyle d}$$ is the dimensionality of the system. Examples include charge-charge interactions between ions and dipole-dipole … See more WebAt the end of the simulation, we have a sequence of points in the phase-space called a trajectory. Molecular dynamics simulations are approximate in two senses. First, they …
