molekyldynamik

Molekyldynamik is a computational method used to study the physical movements of atoms and molecules. It simulates the interactions between particles over time by numerically solving Newton's equations of motion. Essentially, it tracks how atoms and molecules move and interact based on their masses and the forces acting between them.

The process involves defining a system of atoms and molecules, specifying their initial positions and velocities, and then calculating the forces between them using a force field. This force field is a mathematical model that describes the potential energy of the system based on the positions of the atoms. The simulation then iteratively updates the positions and velocities of each particle over very small time steps, typically on the order of femtoseconds.

By simulating these movements, researchers can gain insights into a wide range of phenomena. This includes understanding protein folding, drug binding, material properties, and chemical reactions. Molekyldynamik allows for the observation of dynamic processes that are too fast or complex to be studied experimentally. The accuracy of the simulation depends heavily on the quality of the force field and the computational resources available.
