# LAMMPS

```{versionchanged} 2.12
LAMMPS is no longer a build-time dependency. eOn loads `liblammps` at
runtime via `dlopen`. Install LAMMPS in the same environment.
```

## Quick install

```{code-block} bash
# conda-forge (recommended)
conda install -c conda-forge lammps

# Or pixi
pixi add lammps
```

No eOn rebuild required. See the [LAMMPS potential guide](project:../user_guide/lammps_pot.md)
for usage details.
