Re: [QE-users] [External Email] Relax calculations stops after few iterations
Hi Poonam, It looks like your unit cell is very small, so the pressure is (kbar) P=82027.53 which looks unphysical. I think increasing the unit cell may help.

[QE-users] fundamental questions about force convergence criterion
Greeting, QE users and experts, I am a little bit confused about force information printed by pw.x: --START--- Forces acting on atoms (cartesian axes, Ry/au): atom1 type 1 force =-0.10850.0. atom2 type 2 force = 0.10850.0. The non-local contrib. to forces atom1 type 1 force =-1.192472400.0. atom2 type 2 force = 2.358699680.0. The ionic contribution to forces atom1 type 1 force =10.24429006 -0.0. atom2 type 2 force = -10.244290060. -0. The local contribution to forces atom1 type 1 force =-9.054122270.0. atom2 type 2 force = 7.899444060.0. The core correction contribution to forces atom1 type 1 force = 0.001873260.0. atom2 type 2 force =-0.01425971 -0. -0. The Hubbard contrib.to forces atom1 type 1 force = 0.0.0. atom2 type 2 force = 0.0.0. The SCF correction term to forces atom1 type 1 force = 0.0019 -0.0. atom2 type 2 force = 0.0184 -0. -0. DFT-D3 dispersion contribution to forces: atom1 type 1 force = 0.02640.0. atom2 type 2 force =-0.0264 -0. -0. Total force = 0.15 Total SCF correction = 0.02 DFT-D3 dispersion Force = 0.04 ---END (I just take optimization of CO molecule as example.) What make me confused are, 1. What do two lines below "Forces acting on atoms..." mean? I tried to add all "contribution" terms (from non-local to dispersion) of one atom together but found not to equal to 0.1085. 2. I find that "Total SCF correction" roughly equals to "1.9E-7 + 1.84E-6", and "DFT-D3 dispersion Force" roughly equals to "|2.64E-6|+|-2.64E-6|". However, I don't know how to obtain "Total force = 1.5E-5", I tried to sum over all terms of each atom above it, took their absolute values and add together, but result was 8.35E-4, not 0.15 (1.5E-5). Any answers will be appreciated, thanks in advance! Best regards! Yike Huang, PhD candidate.

Re: [QE-users] Monitoring the ion velocities in pw.x
Hi Natalie I am not aware of any way to monitor the velocities during a MD run with the PWscf code. It uses plain Verlet (not velocity Verlet) and this is likely the reason why velocities are a little bit neglected. Thank you for the info about the existence of "ion_velocities='from_input'". I just added it to the documentation. Does anybody know about the units for velocities? Should be Ry a.u., can anybody confirm?

Re: [QE-users] Monitoring the ion velocities in pw.x
Dear Paolo, Thanks for the information. The input velocities seem to be OK when we use the units of bohr/Rytime when Ry=hbar/Ry. Hopefully this is correct.After I sent the email I finally read the code more carefully and realized that the velocity is calculated internally as vel(t)=(tau(t+dt)-tau(t-dt)/(2dt).Since the tau values are in the output, we could then find the velocity values in postprocessing. Thanks again. Natalie N. A. W.

[QE-users] Error in pp.x calculation
Dear Quantum Espresso community: I followed the steps of the tutorial from Christoph Wolf: (https://christoph-wolf.at/2018/05/02/dipole-correction-in-quantum-espresso/). I did scf calculations and now I need to carry out the pp.x calculations.

[QE-users] Wired Results of band structure plotting
Dear All, I could finish the band calculation successfully and obtain the band.dat file, which is shown below, and it looks fine to me. &plot nbnd= 328, nks= 301 / 0.750148 0.721602 0.203942 -79.712 -79.712 -79.712 -79.705 -79.705 -79.705 -79.704 -79.704 -79.703 -79.502 -79.502 -79.502 -79.495 -79.495 -79.495 -79.494 -79.494 -79.493 -44.235 -44.235 -44.235 -44.225 -44.225 -44.225 -44.202 -44.201 -44.201 -44.121 -44.121 -44.120 -44.113 -44.113 -44.113 -44.095 -44.095 -44.095 -42.491 -42.491 -42.491 -42.484 -42.484 -42.484 -42.458 -42.458 -42.458 -42.386 -42.386 -42.386 -42.382 -42.382 .. Then, I use the following file (drawband.in) to extract the band structure. band.dat -1.0 1.0 band.xmgr band.ps 15.2054 1.0 15.2054 Here is the script I used for plotting band structure. #!/bin/bash #SBATCH --partition=workq #SBATCH --job-name="espresso" #SBATCH --nodes=1 #SBATCH --time=24:00:00 #SBATCH --exclusive #SBATCH --err=std.err #SBATCH --output=std.out #--# #export ESPRESSO_USE="" # This is the default #export ESPRESSO_USE=_scalapack # This is the scalapack version module load espresso/6.5 export OMP_NUM_THREADS=1 #--# echo "The job "${SLURM_JOB_ID}" is running on "${SLURM_JOB_NODELIST} #--# srun --ntasks=1 --hint=nomultithread --ntasks-per-node=32 --ntasks-per-socket=16 --ntasks-per-core=1 --mem-bind=v,local ${ESPRESSO_HOME}/bin/plotband.x < drawband.in > drawband.out rm -r pr.* After I run the script, I obtain three .xmgr files. (band.xmgr.1.1, band.xmgr.2.1 and band.xmgr.3.1). I suppose there should be only one .xmgr file generated after I run plotband.x code. Why are there three .xmgr files generated? I plot all data in these three files and the band structure looks wrong as well. Would anyone please give me some suggestions on the solution? Thank you very much.
