1. 自恰計算 INPUT: &control calculation='scf' restart_mode='from_scratch', pseudo_dir = './', outdir='./' prefix='cu' / &system ibrav = 2, celldm(1) =6.73, nat= 1, ntyp= 1, ecutwfc = 25.0, ecutrho = 300.0 occupations='smearing', smearing='gaussian', degauss=0.02 / &electrons diagonalization='david' conv_thr = 1.0e-8 mixing_beta = 0.7 / ATOMIC_SPECIES Cu 63.55 Cu.pz-d-rrkjus.UPF ATOMIC_POSITIONS Cu 0.0 0.0 0.0 K_POINTS (automatic) 8 8 8 0 0 0 這一步正常 2. 得到較密K點 并且 非自恰計算: INPUT &control calculation='nscf' prefix='cu' pseudo_dir='./' outdir='./' / &system ibrav=2 celldm(1)=6.73 nat=1 ntyp=1 ecutwfc=25.0 ecutrho=300 nbnd=8 / &electrons conv_thr=1.0e-8 mixing_beta=0.7 / ATOMIC_SPECIES Cu 63.55 Cu.pz-d-rrkjus.UPF ATOMIC_POSITIONS Cu 0.0 0.0 0.0 K_POINTS 216 0.000000 0.000000 0.000000 1.00 -0.200000 0.200000 -0.200000 1.00 -0.400000 0.400000 -0.400000 1.00 .... .... 執(zhí)行命令 pw.x < cu.fs.in > cu.fs.out 出現(xiàn)如下錯誤: Program PWSCF v.4.3.2 starts on 9Apr2014 at 22:29:17 This program is part of the open-source Quantum ESPRESSO suite for quantum simulation of materials; please cite "P.
