How To Install lammps on CentOS 8

lammps is Molecular Dynamics Simulator

Introduction

In this tutorial we learn how to install lammps on CentOS 8.

What is lammps

LAMMPS is a classical molecular dynamics code, and an acronym for Large-scale Atomic/Molecular Massively Parallel Simulator. LAMMPS has potentials for soft materials (biomolecules, polymers) and solid-state materials (metals, semiconductors) and coarse-grained or mesoscopic systems. It can be used to model atoms or, more generically, as a parallel particle simulator at the atomic, meso, or continuum scale. LAMMPS runs on single processors or in parallel using message-passing techniques and a spatial-decomposition of the simulation domain. The code is designed to be easy to modify or extend with new functionality.

We can use yum or dnf to install lammps on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install lammps.

Install lammps on CentOS 8 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

The output should look something like this:
