The force field for molecular simulation of ionic liquids is available for download from the web pages of Agilio Padua.
Several tools are also available on that page:
- ilff: force-field parameter database for molecular dynamics simulation of ionic liquids.
- fftool: a tool to build force field files and initial configurations for molecular dynamics using LAMMPS or DL_POLY.
- compute fep: methods for free energy calculations with LAMMPS.
