{ "title" "Elastic constants for CHN in AFLOW crystal prototype AB9C9_aP38_2_i_9i_9i at zero temperature and pressure v000" "description" "Given the zero-pressure, zero-temperature structure of CHN in AFLOW crystal prototype AB9C9_aP38_2_i_9i_9i, this Test computes the corresponding elastic constants using numerical differentiation. By default, the Hessian of the energy w.r.t. strain is used, but depending on the computed uncertainty and material symmetry violation, the Jacobian of the stress w.r.t. strain may be used instead."
