請問我進(jìn)行relax計算的時候,原子的坐標(biāo)完全沒有變化,這正常嗎? 輸出文件(部分結(jié)果): the Fermi energy is -3.2199 ev ! total energy = -77.04604446 Ry Harris-Foulkes estimate = -77.04604446 Ry estimated scf accuracy < 4.5E-13 Ry The total energy is the sum of the following terms: one-electron contribution = -58.02346949 Ry hartree contribution = 32.67217156 Ry xc contribution = -16.21517278 Ry ewald contribution = -35.45905453 Ry smearing contrib.
