ARCHER2 Introduction to LAMMPS Session 1

LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator) is a widely-used classical molecular dynamics (MD) code. This C++ code is easy to use, incredibly versatile, and parallelised to run efficiently on both small-scale personal computers and CPU/GPU/CPU&GPU HPC clusters. As of 2023, LAMMPS has been used, to some degree, in over 40,000 publications in fields as varied as chemistry, physics, material science, granular and lubricated-granular flow.The course will be divided into two parts: The first part will be an introduction to setting up and running an MD simulation using LAMMPS. We will begin by running a simulation of a Lennard-Jones fluid before delving deeper into how simulations can be set up and run in LAMMPS. The second part will go over advanced input commands, property calculations, outputs, input generation, data post-processing, and trajectory visualization.
