ASE is a set of tools and Python modules for setting up, manipulating, running, visualizing and analyzing atomistic simulations.

Webpage: https://ase-lib.org/

Requirements

Optional:

  • Flask (for ase.db web-interface)

  • spglib (for symmetry operations)

Installation

To install the latest release:

pip install ase

To install the development version:

pip install git+https://gitlab.com/ase/ase.git

Testing

Please run the tests:

$ ase test  # takes 1 min.

and send us the output if there are failing tests.

Contact

Feel free to create Merge Requests and Issues on our GitLab page: https://gitlab.com/ase/ase

Example

Geometry optimization of hydrogen molecule with NWChem:

>>> from ase import Atoms
>>> from ase.optimize import BFGS
>>> from ase.calculators.nwchem import NWChem
>>> from ase.io import write
>>> h2 = Atoms('H2',
               positions=[[0, 0, 0],
                          [0, 0, 0.7]])
>>> h2.calc = NWChem(xc='PBE')
>>> opt = BFGS(h2, trajectory='h2.traj')
>>> opt.run(fmax=0.02)
BFGS:   0  19:10:49    -31.435229     2.2691
BFGS:   1  19:10:50    -31.490773     0.3740
BFGS:   2  19:10:50    -31.492791     0.0630
BFGS:   3  19:10:51    -31.492848     0.0023
>>> write('H2.xyz', h2)
>>> h2.get_potential_energy()  # ASE's units are eV and Ang
-31.492847800329216

This example requires NWChem to be installed.

$ ase gui h2.traj
