Homework assignment: learning about elastic constants via molecular dynamics simulations
11 Mar 2015 | Teaching Materials | Contributor(s): Alejandro Strachan, David Ray Johnson
In this homework assignment students will use molecular dynamics to compute the elastic constants of metals using an embedded atom model to describe atomic interactions. They will deform a...
Melting via molecular dynamics simulations
10 Mar 2015 | Teaching Materials | Contributor(s): Alejandro Strachan
In this assignment you will use MD simulations to study melting in metals using the nanoMATERIALS simulation tool in nanoHUB. You will build a supercell and heat it up to study its melting. You...

Computational Nanoscience, Lecture 6: Pair Distribution Function and More on Potentials
13 Feb 2008 | Teaching Materials | Contributor(s): Jeffrey C Grossman, Elif Ertekin
In this lecture we remind ourselves what a pair distribution function is, how to compute it, and why it is so important in simulations. Then, we revisit potentials and go into more detail...
Computational Nanoscience, Lecture 5: A Day of In-Class Simulation: MD of Carbon Nanostructures
In this lecture we carry out simulations in-class, with guidance from the instructors. We use the LAMMPS tool (within the nanoHUB simulation toolkit for this course). Examples include...
Computational Nanoscience, Lecture 4: Geometry Optimization and Seeing What You're Doing
In this lecture, we discuss various methods for finding the ground state structure of a given system by minimizing its energy. Derivative and non-derivative methods are discussed, as well as the...
Computational Nanoscience, Lecture 2: Introduction to Molecular Dynamics
30 Jan 2008 | Teaching Materials | Contributor(s): Jeffrey C Grossman, Elif Ertekin
In this lecture, we present and introduction to classical molecular dynamics. Approaches to integrating the equations of motion (Verlet and other) are discussed, along with practical...
