fix nve/dot command :h3

[Syntax:]

fix ID group-ID nve/dot :pre

ID, group-ID are documented in "fix"_fix.html command :ulb,l
nve/dot = style name of this fix command :l
:ule

[Examples:]

fix 1 all nve/dot :pre

[Description:]

Apply a rigid-body integrator as described in "(Davidchack)"_#Davidchack1
to a group of atoms, but without Langevin dynamics. 
This command performs Molecular dynamics (MD)
via a velocity-Verlet algorithm and an evolution operator that rotates 
the quaternion degrees of freedom, similar to the scheme outlined in "(Miller)"_#Miller1. 

This command is the equivalent of the "fix nve/dotc/langevin"_fix_nve_dotc_langevin.html
without damping and noise and can be used to determine the stability range 
in a NVE ensemble prior to using the Langevin-type DOTC-integrator
(see also "fix nve/dotc/langevin"_fix_nve_dotc_langevin.html).
The command is equivalent to the "fix nve"_fix_nve.html.
The particles are always considered to have a finite size.

An example input file can be found in /examples/USER/cgdna/examples/duplex1/.
A technical report with more information on this integrator can be found
"here"_PDF/USER-CGDNA-overview.pdf.

[Restrictions:]

These pair styles can only be used if LAMMPS was built with the
USER-CGDNA package and the MOLECULE and ASPHERE package.  See the "Making
LAMMPS"_Section_start.html#start_3 section for more info on packages.
