Dear all,
i am doing calculation on C2/m monoclinic base centered structure. Infortunately, things don't work;no symmetry in the output and weird structure viewed bu Xcrysden.I checked the coordinates with an other code (Wien2k) where everything seemed to go well, giving the exact number of symmetry operations and the expected structure in Xcrysden. by the way, i am working on Pwscf version 3.2, where the bug ibrav=13 is fixed for good!!!
please help me to figure out the problem, here is my input file:
&control calculation = 'scf' restart_mode = 'from_scratch' pseudo_dir = '/home/hania//pseudo/ outdir = '/home/hania//tmp/' / &system ibrav=13 celldm(1)=31.067, celldm(2)=0.234, celldm(3)=0.5, celldm(4)=-0.213, nat=18 ntyp=3 ecutwfc=35.0 ecutrho=200.0, occupations = 'fixed' / &electrons conv_thr = 1e-6, mixing_beta=0.7, /ATOMIC_SPECIES W 183.84 W.pz-bhs.UPF Bi 208.98 083-Bi-ca-d-vgrp_ji.uspp.UPF O 15.9994 O.pz-van_ak.UPF ATOMIC_POSITIONS alat W 0.4981 0.117 0.15035 W 0.5019 0.117 0.34965 Bi 0.3341 0.000 0.46565 Bi 0.6659 0.000 0.03435 Bi 0.3213 0.000 0.1975 ………………………………………………….. …………………………………………………….
