Dear PWSCF user,<br>I want to calculate the pressure derivative of elastic constant for some of my cubic materials (ScP, ScN in NaCl phase). Please anybody tell me the procedure or refer any paper, where i get the method of calculating the pressure derivative of elastic constants (C11, C12, C44)<br>
