In this first tutorial you will learn how to install Atomsk on your computer, and how to run it.
LAMMPS | Create a Polycrystal
This tutorial explains how to generate 3-D or 2-D polycrystals, containing grains of random or specific positions and orientations.
The mode --polycrystal
, as its name suggests, aims at creating a polycrystal.
In the following examples, a unit cell of aluminium will be used as a seed. Such a unit cell can be generated with:
atomsk --create fcc 4.046 Al aluminium.xsf
LAMMPS | Build LAMMPS with VORONOI package
Quick Start
在未名超算,执行以下命令即可,其他超算平台类似。

LAMMPS | compute voronoi/atom
Syntax
compute ID group-ID voronoi/atom keyword arg ...
- ID, group-ID are documented in compute command
- voronoi/atom = style name of this compute command
- zero or more keyword/value pairs may be appended
keyword = only_group or surface or radius or edge_histo or edge_threshold or face_threshold or neighbors or peratom
