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
|
|
the :doc:`Howto output <Howto_output>` page for an overview of
|
|
LAMMPS output options.
|
|
|
|
The per-atom vector values will be in energy :doc:`units <units>`.
