Dear all
I want to optimize the lattice constant for tetragonal cell. I first start with volume=constant and change the value of c/a ,then at next step for optimized c/a I changed the value of volume in (-4,-2,0,2,4) percent to obtain E(v). Here I want to use murnaghan equation of state by ev.x . Which option do I use in first question :Sc or hex?
Thanks  a lot
