lammps-reaxff

To set up a LAMMPS ReaxFF simulation, you need to generate an input script with pair_style reaxff, map atom types to elements in pair_coeff, and configure QEq. This requires a ReaxFF potential file, a data system file, and proper charge mapping for NVE/NVT/NPT ensembles.

Validating a LAMMPS ReaxFF force field and data file requires ensuring the presence of the ReaxFF potential file, data system, and atom-type to element mapping. Proper input structure with QEq configuration must also be verified for reactive MD simulations.

You can generate an annotated LAMMPS input script for reactive molecular dynamics by using a template generation process. This creates a validated input.lammps file with pair_style reaxff and pair_coeff mappings, which you then customize with your specific data.

Yes, you can run NVE, NVT, and NPT ensembles using the ReaxFF potential in LAMMPS. The simulation setup supports these thermodynamic ensembles along with basic diagnostics and species analysis hooks for studying reactive event pathways.

A LAMMPS ReaxFF simulation requires an atom-type to element mapping to correctly apply the force field through pair_coeff. This mapping links your data file's atom types to the elements defined in the ReaxFF potential file, ensuring proper QEq and charge configuration.

The best way to study reactive event pathways in a CO/H system is by running a short ReaxFF molecular dynamics simulation in LAMMPS with charges and QEq. This involves generating an input template, mapping atom types to elements, and configuring the desired ensemble.
