fix nve command :h3
fix nve/cuda command :h3
fix nve/intel command :h3
fix nve/kk command :h3
fix nve/omp command :h3
[Syntax:]
fix ID group-ID nve :pre
ID, group-ID are documented in "fix"_fix.html command
nve = style name of this fix command :ul
[Examples:]
fix 1 all nve :pre
[Description:]
Perform constant NVE integration to update position and velocity for
atoms in the group each timestep. V is volume; E is energy. This
creates a system trajectory consistent with the microcanonical
ensemble.

Styles with a {cuda}, {gpu}, {intel}, {kk}, {omp}, or {opt} suffix are
functionally the same as the corresponding style without the suffix.
They have been optimized to run faster, depending on your available
hardware, as discussed in "Section_accelerate"_Section_accelerate.html
of the manual. The accelerated styles take the same arguments and
should produce the same results, except for round-off and precision
issues.
These accelerated styles are part of the USER-CUDA, GPU, USER-INTEL,
KOKKOS, USER-OMP and OPT packages, respectively. They are only
enabled if LAMMPS was built with those packages. See the "Making
LAMMPS"_Section_start.html#start_3 section for more info.
You can specify the accelerated styles explicitly in your input script
by including their suffix, or you can use the "-suffix command-line
switch"_Section_start.html#start_7 when you invoke LAMMPS, or you can
use the "suffix"_suffix.html command in your input script.
See "Section_accelerate"_Section_accelerate.html of the manual for
more instructions on how to use the accelerated styles effectively.
