Molecular dynamics (MD) simulations are playing an increasingly important role in many areas of science and engineering, from biology and pharmacy to nanoelectronics and structural materials. Recent breakthroughs in methodologies and in the development of first principles-based interatomic potentials significantly increased the range of applicability of MD and the accuracy of its predictions even for new materials not yet fabricated or synthesized. Such predictive power indicates that MD has the potential to play a key role in guiding the design and optimization of new materials with improved properties tailored for specific applications.
The goal of this short course is to provide an introduction to the theory and algorithms behind MD simulations, describe some of the most exciting recent developments in the field and exemplify with a few applications applications. The series also includes a tutorial on the nano-Materials Simulation Toolkit, an online MD simulation tool available at the nanoHUB. This provides users with a hands-on experience with MD simulations and enables further exploration of some of the concepts described in the lectures.
These lectures were taught at Purdue University during the Fall semester of 2008 as part of MSE597G “Modeling and Simulation of Materials”.
