9 dihedral_style zero command :h3
11 [Syntax:]
13 dihedral_style zero {nocoeff} :pre
15 [Examples:]
17 dihedral_style zero
18 dihedral_style zero nocoeff
19 dihedral_coeff * :pre
21 [Description:]
23 Using a dihedral style of zero means dihedral forces and energies are
24 not computed, but the geometry of dihedral quadruplets is still
25 accessible to other commands.
27 As an example, the "compute
28 dihedral/local"_compute_dihedral_local.html command can be used to
29 compute the theta values for the list of quadruplets of dihedral atoms
30 listed in the data file read by the "read_data"_read_data.html
31 command.  If no dihedral style is defined, this command cannot be
32 used.
34 The optional {nocoeff} flag allows to read data files with a DihedralCoeff
35 section for any dihedral style. Similarly, any dihedral_coeff commands
36 will only be checked for the dihedral type number and the rest ignored.
38 Note that the "dihedral_coeff"_dihedral_coeff.html command must be
39 used for all dihedral types, though no additional values are
40 specified.
