[资源] 弹性计算有福了

ElaStic is AvailableDear Quantum Espresso developers and users,

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