How to find the elastic constatnts at different range of pressure in NaCl structure using quantum esspresso code?

10 March 2018 0 5K Report

I am working on quantum esspresso code. I have calculated the elastic constants of WN compound in NaCl (B1) phase at zero pressure. Now I want to calculate the elastic constants at different pressure like P=10, 20,30,40,50 GPa. So please tell me the process for this.
