improper_style zero command :h3
|
|
|
|
[Syntax:]
|
|
|
|
improper_style zero {nocoeff} :pre
|
|
|
|
[Examples:]
|
|
|
|
improper_style zero
|
|
improper_style zero nocoeff
|
|
improper_coeff * :pre
|
|
|
|
[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 "compute
|
|
improper/local"_compute_improper_local.html 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 "read_data"_read_data.html
|
|
command. If no improper style is defined, this command cannot be
|
|
used.
|
|
|
|
The optional {nocoeff} flag allows to read data files with a ImproperCoeff
|
|
section for any improper style. Similarly, any improper_coeff commands
|
|
will only be checked for the improper type number and the rest ignored.
|
|
|
|
Note that the "improper_coeff"_improper_coeff.html command must be
|
|
used for all improper types, though no additional values are
|
|
specified.
