Hello my dear researchers
I use the elast package in wien2k and castep/materials studio to calculate the elastic constants of solids. I have a material with cubic structure, I make it a 2x1x1 supercell, so it becomes like tetragonal. My question is: to calculate the elastic constants, should I use the commands for cubic structure (C_set_elast_lapw) or those for tetragonal structure (T_set_elast_lapw).
And thanks in advance.
