A package for making Wulff constructions

Project description

WulffPack is a tool for making Wulff constructions, typically for minimizing the energy of nanoparticles. A detailed description of the functionality provided as well as an extensive tutorial can be found in the user guide.

WulffPack constructs both continuum models and atomistic structures for further modeling with, e.g., molecular dynamics or density functional theory.

surface_energies = {(1, 1, 1): 1.0, (1, 0, 0): 1.2}
particle = SingleCrystal(surface_energies)
write('', particle.atoms)

With the help of ASE and Spglib, WulffPack handles any crystalline symmetry. WulffPack also provides the backbone of a web application in the Virtual Materials Lab, in which Wulff constructions for cubic crystals can be created interactively.


In the most simple case, WulffPack can be installed using pip as follows:

pip3 install wulffpack --user

or alternatively:

python3 -m pip install wulffpack --user

WulffPack is based on Python3 and invokes functionality from other Python libraries including
