Dear all,
I'm working with a perovskite, doing preliminary calculations. That
calculations are not needed to be converged, but at least to work
properly for further optimization. I'm trying to do a vc-relax in the
perovskite, in order to obtain the optimal geometry. However, at the
end, I don't have any geometry information. I have made it with
silicon, for instance, and it works.
This is my .in:
&CONTROL
calculation = 'vc-relax'
outdir = '/tmp/'
pseudo_dir = '/home/dlduran/ENERGIAS_RENOVABLES/PSEUDOPOTENCIALES/'
etot_conv_thr = 1e-1
forc_conv_thr = 1e-1
nstep = 2 ! default = 50
/
&SYSTEM
ibrav = 2
a = 12.16160
nat = 114
ntyp = 5
ecutwfc = 10.0
ecutrho = 40.0 ! it should be 4*ecutwfc
