[Pw_forum] about supercell+defect relaxation

[patriot pershing]

dear please:
i have perfectly creating a supercell with N atoms and ntype=1 ( all
atoms are identical) and i have do SCF calculations and others
calculation and processing for a perfect supercell, then i would study
the same supercell but with the addition of one impurities and i
don't know what is the better method to relax the system under
consideration ( VC or ionic Relax method ), in my opinion i think that
the use of VC is more convenable but i would confirm
best regards
