This page gives hints on how to manipulate atoms and groups of atoms to generate
|
|
the set of atomic positions with the ABINIT package.
|
|
|
|
## Introduction
|
|
|
|
ABINIT has some (non-graphical) capabilities to manipulate atoms and group of
|
|
atoms, to help establishing the set of atomic positions in the input file when
|
|
big cells are considered.
|
|
|
|
Explicitly, one or two groups of atoms, forming e.g. a molecule, a cluster, or
|
|
a small primitive cell, can be repeated in arbitrary number, then translated
|
|
and rotated. Then, atoms can be removed, to form e.g. vacancies. See [[nobj]]
|
|
as entry point.
|
|
|
|
The related input variables being used for preprocessing of the input file,
|
|
they are not echoed in the output file ([[INPUT_ONLY]] characteristics).
