Hi, I want to make some test calculations of transport through 'bulk'
copper. Left and right lead shall be equal and the scattering region
should be the same material as the lead itself. My problem is, that I
cant get any results and I can't recognize any mistakes in my input
cards -> my inputcards are:
# self-consistent calculation for Cu bulk
&control
calculation='scf'
restart_mode='from_scratch',
pseudo_dir = '$PSEUDO_DIR/',
outdir='$TMP_DIR/'
prefix='cu'
/
&system
ibrav = 1
celldm(1) = 6.719
nat= 1,
ntyp= 1,
ecutwfc = 40.0,
occupations='smearing',
smearing='methfessel-paxton',
degauss=0.01
/
&electrons
conv_thr = 1.0e-12
mixing_beta = 0.5
/
ATOMIC_SPECIES
Cu 63.55 Cu.pz-d-rrkjus.UPF
ATOMIC_POSITIONS
Cu 0.0 0.0 0.0
K_POINTS (automatic)
16 16 16 0 0 0
# complex bands of Copper along the 001 direction K_perp=0
cat > cu.cond.in << EOF
&inputcond
oudir='$TMP_DIR/'
prefixl='cu'
band_file ='bands.cu'
ikind=0
energy0=10.d0
denergy=-0.1d0
ewind=1.d0
epsproj=1.d-3
delgep = 1.d-12
cutplot = 2.d0

# transmission calculation for the perfect copper contact
cat > cutrans.cond.in << EOF
&inputcond
outdir='$TMP_DIR/',
prefixl='cu',
prefixs='cu',
tran_file='trans.cu',
ikind=1,
energy0=2.95d0,
denergy=-0.1d0,
ewind=1.d0,
epsproj=1.d-3,
nz1 = 1

I get the error message:
task # 1
from in init_cond : error # 172992232
wrong nrztot
I would be thankful for every hint that you might give me...
