REBO cutoff for short range interactions. in the example there is a Python source, but it doesn't matter: you can include any file but you have to write the full file name. with the size of the cutoff since larger supercells are needed and: more terms must be computed. You will need to adjust the values in the PARM. A TIP4P model is run with LAMMPS using either this command for a cutoff model: pair_style lj/cut/tip4p/cut. Intro of LAMMPS¶ LAMMPS is a simulation software for particle systems. LAMMPS is a classical molecular dynamics code that models an ensemble of particles in a liquid, solid, or gaseous state. Once again, thank you for your immediate Is there something I need to look at or do you just wanted to share them? bond_graph_cutoff: is the threshold used in determining what is a physical bond, what is not. This parameter is only relevant for a twin-range cut-off setup with switched potentials. This means it can vary from one simulation to the next which may not be desirable for matching a KSpace solver to a pre-tabulated pairwise potential. Separate values can be specified for: harmonic (cutoff_harm) and cubic (cutoff_cubic) terms, or a single: value for both. 2012-08-01. If I just use cut-off at a certain distance (for electrostatics), the energies match very well, but only when I use Ewald or PPPM there are discrepancies in electrostatic energies (both short and long ranges).

UPDATE 11 June 2012: The version posted on 26 April 2012 had an extra line in the header and did not work with LAMMPS. Typically these are good values values for minimizing the time for neighbor list construction. Bonds and angles reported in the trajectory file rely on this cutoff. > I have attached the corresponding tutorials > with lammps as the MD package. Using this form of output avoids the need to convert LAMMPS snapshots to PDB files.
