<div dir="ltr"><div>Dear Malte,</div><div> My test system is a U
bearing compound. Since I intended to carry on a phonon calculation I
used a very small force convergence threshold (forc_conv_thr) of 1.0D-7
and an even smaller convergence for total energy (etot_conv_thr) of
1.0D-9 for ionic minimization. Consequently I had to choose a lower
convergence threshold for self-consistency (conv_thr in &ELECTRONS)
of 1.0D-12 . The k-point grid is 8*8*9 (optimized). <br></div><div>
The cut-off energy and k-pt grid are correlated. But does my choice of
thresholds did push the cut-offs higher ? <br></div><div>
By the way the system I am dealing with is a less explored one. no
electronic properties so no band gap etc are reported. I chose to go
with 1st order methfessel-paxton smearing for not knowing whether it is
an insulator or semiconductor .<br></div><div>Thank you in advance.</div><br clear="all"><br>-- <br><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr">Sudip Kumar Mondal<div>DST-INSPIRE Junior Research Fellow</div><div>High Pressure Temperature Laboratory<br></div><div>Dept.
