<P>The local data is generated by looping over all the atoms owned on a

[Description:]
|
||||
|
||||
Define a computation that stores the specified attributes as global
|
||||
data so it can be accessed by other "output
|
||||
commands"_Section_howto.html#4_15. If the input attributes refer to
|
||||
bond information, then the number of datums generated, aggregated
|
||||
across all processors, equals the number of bonds in the system.
|
||||
|
||||
If multiple input attributes are specified then they must all generate
|
||||
the same amount of information, so that the resulting local array has
|
||||
the same number of rows for each column. This means that only bond
|
||||
attributes can be specified together, or angle attributes, etc. Bond
|
||||
and angle attributes can not be mixed in the same compute
|
||||
property/local command.
|
||||
|
||||
The local data is generated by looping over all the atoms owned on a
|
||||
processor and extracting bond, angle, etc info. For bonds, info about
|
||||
an individual bond will only be included if both atoms in the bond are
|
||||
in the specified compute group. Likewise for angles, dihedrals, etc.
|
||||
|
||||
Note that as atoms migrate from processor to processor, there will be
|
||||
no consistent ordering of the entries within the local vector or array
|
||||
from one timestep to the next. The only consistency that is
|
||||
guaranteed is that the ordering on a particular timestep will be the
|
||||
same for local vectors or arrays generated by other compute commands.
|
||||
For example, output from the "compute
|
||||
bond/local"_compute_bond_local.html command can be combined with bond
|
||||
atom indices from this command and output by the "dump
|
||||
local"_dump.html command in a consistent way.
|
||||
|
||||
The {batom1} and {batom2} attributes refer the atom IDs of the 2 atoms
|
||||
in each "bond"_bond_style.html. The {btype} attribute refers to the
|
||||
type of the bond, from 1 to Nbtypes = # of bond types. The number of
|
||||
bond types is defined in the data file read by the
|
||||
"read_data"_read_data.html command. The attributes that start with
|
||||
"a", "d", "i", refer to similar values for "angles"_angle_style.html,
|
||||
"dihedrals"_dihedral_style.html, and "impropers"_improper_style.html.
|
||||
|
||||
[Output info:]
|
||||
|
||||
This compute calculates a global vector or global array depending on
|
||||
the number of input values. The length of the vector or number of
|
||||
rows in the array is the number of molecules. If a single input is
|
||||
specified, a global vector is produced. If two or more inputs are
|
||||
specified, a global array is produced where the number of columns =
|
||||
the number of inputs. The vector or array can be accessed by any
|
||||
command that uses global values from a compute as input. See "this
|
||||
section"_Section_howto.html#4_15 for an overview of LAMMPS output
|
||||
options.
