Dear All, My question is about the cohesive energy. In example01 ni.scf.cg.out, total energy is calculated as -85.72249139 ryd (or ~1165.8eV) for one atom in fcc structure (nat=1 and ibrav=2). How to use this info to get cohesive energy of Ni, which is about 5eV? Thanks very much in advance for your help. Best regards, Yong
