improper_style zero command¶
Syntax¶
improper_style zero
Examples¶
improper_style zero
improper_coeff *
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 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 command. If no improper style is defined, this command cannot be used.
Note that the improper_coeff command must be used for all improper types, though no additional values are specified.
