compute bond command

Syntax

compute ID group-ID bond
  • ID, group-ID are documented in compute command
  • bond = style name of this compute command

Examples

compute 1 all bond

Description

Define a computation that extracts the bond energy calculated by each of the bond sub-styles used in the bond_style hybrid command. These values are made accessible for output or further processing by other commands. The group specified for this command is ignored.

This compute is useful when using bond_style hybrid if you want to know the portion of the total energy contributed by one or more of the hybrid sub-styles.

Output info:

This compute calculates a global vector of length N where N is the number of sub_styles defined by the bond_style hybrid command, which can be accessed by indices 1-N. These values can be used by any command that uses global scalar or vector values from a compute as input. See the Howto output doc page for an overview of LAMMPS output options.

The vector values are “extensive” and will be in energy units.
