dihedral_style zero command¶
Syntax¶
dihedral_style zero [nocoeff]
Examples¶
dihedral_style zero
dihedral_style zero nocoeff
dihedral_coeff *
Description¶
Using a dihedral style of zero means dihedral forces and energies are not computed, but the geometry of dihedral quadruplets is still accessible to other commands.
As an example, the compute dihedral/local command can be used to compute the theta values for the list of quadruplets of dihedral atoms listed in the data file read by the read_data command. If no dihedral style is defined, this command cannot be used.
The optional nocoeff flag allows to read data files with a DihedralCoeff section for any dihedral style. Similarly, any dihedral_coeff commands will only be checked for the dihedral type number and the rest ignored.
Note that the dihedral_coeff command must be used for all dihedral types, though no additional values are specified.
Restrictions¶
none
Default¶
none
