Prerequisites for working with LAMMPS

Before we start working with LAMMPS, we need to get a few things up and running for hassle-free execution:

• Downloading the source code
• Installing dependencies
• Downloading MPICH

We'll look at the preceding points in the following sections.

Downloading the source code

You can download the LAMMPS source code from GitHub by entering the following command in the terminal:

git clone https://github.com/lammps/lammps.git 

If, instead, the source code is downloaded from other sources (for example, the LAMMPS download page at https://lammps.sandia.gov/download.html), please make sure to unzip accordingly.

apt install build-essential
apt install cmake
apt install gfortran    
apt update
apt upgrade

As the preceding components are being installed, progress...
