  LAMMPS is a widely popular classical Molecular Dynamics package. It was
designed for materials modeling but it is well prepared for simulations in Soft
Matter. The use packages like LAMMPS has advantages and disadvantages. The main
advantage is the optimization of the methods, mainly for parallel computing.
The main disadvantage is that, due to the complexity of the code, it ha long
learning curve. One purpose of these notes is to shorten that curve for
researchers are starting to use LAMMPS to simulate soft active matter. In these
notes, we first discuss some Molecular Dynamics methods implemented in LAMMPS.
We present an hands-on introduction to first-time users and we finish with an
advanced hands-on section, where we implement and test Active Brownian
particles simulations.
