Output stop update after wannier90

[sevenel]

Dear all,
I want to calculate the mobility of 2D InSe in the paper Nano Lett. 2019, 19, 1774−1781,
This is my input file

Code: Select all

&inputepw
 prefix='InSe'
 outdir='./'
 dvscf_dir='../save'
 
 elph=.true.
 epbwrite = .true.
 epbread = .false.
 epwwrite=.true.
 epwread=.false.
 lpolar = .true.
 vme = 'wannier'
 use_ws = .true.
 
 wannierize=.true.
 bands_skipped='exclude_bands = 1-12'
 nbndsub=14
 dis_froz_max =  4.0
 dis_froz_min = -7.5
 proj(1)='In:s,p'
 proj(2)='Se:p'

 efermi_read = .true.  
 fermi_energy= -1.4537
 fsthick = 100
 nstemp = 1
 temps = 0.075
 degaussw = 0.001
 
 band_plot = .true.
 filkf='KPOINTS1'
 filqf='KPOINTS1'
 nk1 = 12
 nk2 = 12
 nk3 = 1
 nq1 = 12
 nq2 = 12
 nq3 = 1
/

and the output stop update after wannier90,

and when I go to the node of calculating, I found only part of the task is running (8/28),

only part of the task is running

anyone can give me some advice?

Hi Sevenel,

Please make sure your "dvscf_dir='../save'" directory contains *.dyn_q*, *.dvscf_q*, and *.phsave/patterns.*.

Best,
Hari

Dear Hari,
Thanks for your advice, and I confirm that the ../save/ folder contains *.dyn_q*, *.dvscf_q*, and *.phsave/patterns.*.
Any other suggestions?

Dear zhenqing:

Symmetries of Bravais lattice: 24
Symmetries of crystal: 2

The information above doesn't make sense. Could you provide the inputs and full outputs of non-self-consistent and EPW calculations?
In the present and previous versions of EPW, some input flags of pw.x for the symmetry such as nosym, etc. are problematic.

Sincerely,

H. Lee

Dear H. Lee,
Thanks for your advice, and I solved the problem with the following tips

In order to generate the q-point list from the symmetry of the system, we shouldn’t use nosym=.true. in nscf calculations. If nscf calculation generates more k points than you provided, you have to use calculation='bands' instead of calculation='nscf' without using any symmetry-related flag
such as nosym.

Best wishes

Dear zhenqing,
I encountered the same problem as you, but I didn't use the parameter- nosym in the process. And I also tried to change 'nscf' to 'bands' in non-self consistent computing, but the same problem still occurs. Do you have any good ways to share?
Best regards,

Hi xiangyue,

Could you provide the inputs and all outputs of nscf and EPW calculations?

Best,

Dear Hari Paudyal,
The attached are my inputs and outputs files in the epw folder.
Best regards,

Hi Xiangyue,

Basically you can attach scf.in, scf.out, nscf.in, nscf.out, epw.in, and epw.out so that we can read them.

Best,
Hari Paudyal
