Description
|
|
"""""""""""
|
|
|
|
Using an improper style of zero means improper forces and energies are
|
|
not computed, but the geometry of improper quadruplets is still
|
|
accessible to other commands.
|
|
|
|
As an example, the :doc:`compute improper/local <compute_improper_local>` command can be used to
|
|
compute the chi values for the list of quadruplets of improper atoms
|
|
listed in the data file read by the :doc:`read_data <read_data>`
|
|
command. If no improper style is defined, this command cannot be
|
|
used.
|
|
|
|
Note that the :doc:`improper_coeff <improper_coeff>` command must be
|
|
used for all improper types, though no additional values are
|
|
specified.
