JARVIS-Tools: an open-source software package for data-driven atomistic materials design

NIST-JARVIS (Joint Automated Repository for Various Integrated Simulations) is an integrated framework for computational science using density functional theory, classical force-field/molecular dynamics and machine-learning. The jarvis-tools package consists of scripts used in generating and analyzing the dataset. The NIST-JARVIS official website is: https://jarvis.nist.gov . This project is a part of the Materials Genome Initiative (MGI) at NIST (https://mgi.nist.gov/).

Some important features

• Software workflow tasks: VASP, Quantum Espresso, Wien2k BoltzTrap, Wannier90, LAMMPS, Scikit-learn, TensorFlow, LightGBM.

• HPC clusters: PBS and SLURM.

• Examples: Notebooks and test scripts to explain the package.

• Available datasets: Summary of several datasets .

Example function

>>> from jarvis.core.atoms import Atoms
>>> box = [[2.715, 2.715, 0], [0, 2.715, 2.715], [2.715, 0, 2.715]]
>>> coords = [[0, 0, 0], [0.25, 0.25, 0.25]]
>>> elements = ["Si", "Si"]
>>> Si = Atoms(lattice_mat=box, coords=coords, elements=elements)
>>> density = round(Si.density,2)
>>> print (density)
2.33
>>>
>>> from jarvis.db.figshare import data
>>> dft_3d = data(dataset='dft_3d')
>>> print (len(dft_3d))
36099
>>> from jarvis.io.vasp.inputs import Poscar
>>> for i in dft_3d:
...     atoms = Atoms.from_dict(i['atoms'])
...     poscar = Poscar(atoms)
...     jid = i['jid']
...     filename = 'POSCAR-'+jid+'.vasp'
...     poscar.write_file(filename)
>>> dft_2d = data(dataset='dft_2d')
>>> print (len(dft_2d))
1070
>>> for i in dft_2d:
...     atoms = Atoms.from_dict(i['atoms'])
...     poscar = Poscar(atoms)
...     jid = i['jid']
...     filename = 'POSCAR-'+jid+'.vasp'
...     poscar.write_file(filename)
