Hello Dear QE users,
I hope everybody is doing well. I am using hp.x to calculate hubbard
parameters for my structure. The first scf input is as follow:
&control
calculation='scf',
verbosity = 'low',
restart_mode = 'from_scratch',
prefix = 'my_file',
tstress = .true.,
tprnfor = .true.,
forc_conv_thr = 1.0D-4 ,
pseudo_dir ='./',
outdir='./tmp',
nstep=3000,
wf_collect=.true.
verbosity='high'
/
&SYSTEM
ibrav=0,
nat=10,
ntyp=3,
ecutwfc=42,
ecutrho=420,
occupations='smearing',
degauss=0.001,
smearing='mv',
nspin = 2,
starting_magnetization(1) = 0.5,
starting_magnetization(2) = -0.5,
lda_plus_u = .true.,
lda_plus_u_kind = 0,
U_projection_type = 'atomic',
Hubbard_U(1) = 1.d-8
Hubbard_U(2) = 1.d-8
/
&electrons
mixing_beta = 0.7,
conv_thr = 1.0d-10,
electron_maxstep=600,
/
&IONS
ion_dynamics = 'bfgs',
/
&cell
cell_dynamics = 'bfgs',
/
