compute ke/atom command :h3

[Syntax:]

compute ID group-ID ke/atom :pre

ID, group-ID are documented in "compute"_compute.html command
ke/atom = style name of this compute command :ul

[Examples:]

compute 1 all ke/atom :pre

[Description:]

Define a computation that calculates the per-atom translational
kinetic energy for each atom in a group.

The kinetic energy is simply 1/2 m v^2, where m is the mass and v is
the velocity of each atom.

The value of the kinetic energy will be 0.0 for atoms not in the
specified compute group.

[Output info:]

This compute calculates a per-atom vector, which can be accessed by
any command that uses per-atom values from a compute as input.  See
"Section_howto 15"_Section_howto.html#howto_15 for an overview of
LAMMPS output options.

The per-atom vector values will be in energy "units"_units.html.

[Restrictions:] none

[Default:] none
