Dear Dev, I also have never used this feature of the code but Doc directory has useful documents when you need answers: Doc/eps_man.tex It is clearly stated there that "the non-local contribution due to the pseudopotential is neglected. Actually the correction to the matrix element that take

[Pw_forum] equilibrium lattice constant determination

2009-09-27 Thread Emine Kucukbenli
Dear Sreekar, Could you please clarify why, in your opinion, energy/(unit cell volume) vs (unit cell volume) should give the minimum but not energy vs (unit cell volume)? Since you are trying to find the gs lattice constant, I am assuming you consider harmonic approximation around gs lattice
