Hi there, I am trying to use the tip3p model to simulate water. I tried both sets of tip3p parameters as provided by: This manual documents the collective variables module (Colvars), a portable software that interfaces mul in LAMMPS. One of these parameters is the conguration le or the conguration text for the module itself, whose syntax is described in3.
2and in the following sections. These are the additional parameters (in real units) to set for O and H atoms and the water molecule to run a rigid TIP3PCHARMM model with a cutoff.
7 TIP3P water model The TIP3P water model as implemented in CHARMM (MacKerell) specifies a 3site rigid water molecule with charges and LennardJones parameters assigned to each of the 3 atoms Table of Contents LAMMPS Documentation. 1 PDF file of the entire manual, generated by htmldoc. The content for this manual is part of the LAMMPS distribution. You can build a local copy of the Manual as HTML pages or a PDF file, by following the steps on the Manual build doc page. There is also a Developer.
pdf document which gives a brief description of the basic code structure of LAMMPS. zhangliqun: Can someone send me a box of preequilibrated water? I know some guys built different sized water box using tip3ptip4p model for others to download. But I am not sure where they are. A water model is defined by its geometry, together with other parameters such as the atomic charges and LennardJones parameters. In computational chemistry, a water model is used to simulate and thermodynamically calculate water clusters, liquid water, and aqueous solutions with explicit solvent.
Table of Contents LAMMPS Documentation. 1 Water models are useful given the basis that, if the (known but hypothetical) model (that is, computer water) can successfully predict the physical properties of liquid water, then the (unknown) structure of liquid water is determined.

The potential parameters for TIP3P, TIP4P, SPC and SPC(E) are provided here. The potential parameters for TIP3P, TIP4P, SPC and SPC(E) are provided here.
