filkf and filqf

Post by osama jalil »

Hi EPW community;
How we can generate files for filkf and filqf like below. I have taken this from an example. But when I generate my grid using wannier kmesh.pl, xcrysden or use some existed kpath.py. I cant generate the file like this and code did't give me reuslt. Thanks in avdance.

Hi Osama,

This can be done through pw.x (for a scf calculation) with the following modifications in the input (test.in).

(1) verbosity = 'high'
(2)
K_POINTS crystal_b
3
0.5000 0.500 0.500 50
0.0000 0.000 0.000 50
0.0000 0.500 0.500 1

(3) run your test.in,
pw.x <test.in

after when the k-points are printed with pw.x, you can kill your job (do not need to finish the calculation). You can now copy the k-points to make in this format. I know this needs some exercise, but works if you do not have any scripts to generate the k-points along a path.

Best,
