Yes, with distortions the symmetry gets lower and you may get different multiplicity. I can see at least ONE rule that you violated: Used identical RMTs within such calculations. You cannot change RMTs from one to the next structure, since your energies become non-comparable. Your Al-RMT sho

Dear wien2k community I wanted to get the elastic constants of a cubic structure using elastic module in wien2k. I completed the calculation I am getting unacceptable values as below in GPa: c11= -36037.828466 c12=18133.340459 c44= 54.083125 I used the optimized correct structure
