<br>
I am happy to announce here the first version of the ElaStic code is available. <span>ElaStic</span> is an open-source Python implementation for the calculations of <span>elastic</span> constants of crystalline materials. It can be used to obtain full second-order <span>elastic</span> tensors for all crystal lattice types and third-order <span>elastic</span> tensors for cubic, hexagonal, and rhombohedral crystals. The package has a rich set of features for transforming the <span>elastic</span> constants into any Cartesian coordinate system and computing <span>elastic</span> moduli with different averaging methods.
<span>ElaStic</span> is interfaced with the
density-functional codes exciting, WIEN2k, and <b>Quantum Espresso</b> for
computing the energy and stress matrices of deformed crystals. <span>ElaStic</span> can be downloaded from <a href="http://exciting-code.org/elastic" target="_blank">http://exciting-code.org/<span>elastic</span></a> together with its documentation and recently published paper.<br>
