Description
|
|
"""""""""""
|
|
|
|
Define a computation that extracts the improper energy calculated by
|
|
each of the improper sub-styles used in the :doc:`improper_style hybrid <improper_hybrid>` command. These values are made
|
|
accessible for output or further processing by other commands. The
|
|
group specified for this command is ignored.
|
|
|
|
This compute is useful when using :doc:`improper_style hybrid <improper_hybrid>` if you want to know the portion of the
|
|
total energy contributed by one or more of the hybrid sub-styles.
|
|
|
|
Output info
|
|
"""""""""""
|
|
|
|
This compute calculates a global vector of length :math:`N`, where :math:`N` is
|
|
the number of sub_styles defined by the
|
|
:doc:`improper_style hybrid <improper_style>` command.
|
|
These styles can be accessed by the indices 1 through :math:`N`.
|
|
These values can be used by any command that uses global scalar or vector
|
|
values from a compute as input. See the :doc:`Howto output <Howto_output>`
|
|
page for an overview of LAMMPS output options.
|
|
|
|
The vector values are "extensive" and will be in energy
|
|
:doc:`units <units>`.
