# angle_style zero command

## Syntax

angle_style zero nocoeff


## Examples

angle_style zero
angle_style zero nocoeff
angle_coeff *
angle_coeff * 120.0


## Description

Using an angle style of zero means angle forces and energies are not computed, but the geometry of angle triplets is still accessible to other commands.

As an example, the compute angle/local command can be used to compute the theta values for the list of triplets of angle atoms listed in the data file read by the read_data command. If no angle style is defined, this command cannot be used.

The optional nocoeff flag allows to read data files with AngleCoeff section for any angle style. Similarly, any angle_coeff commands will only be checked for the angle type number and the rest ignored.

Note that the angle_coeff command must be used for all angle types. If specified, there can be only one value, which is going to be used to assign an equilibrium angle, e.g. for use with fix shake.
