How to integrate CHGCAR values in Z-direction of a cell?

Hi i asked this query at other forum. But also just found that some similar tool is there in vtst tools as well. So, asking the same here as well, please. --- i did a CHGCAR file written for both optimised and non-optimised (single point run) runs. So, i have two CHGCAR files. Using vaspkit i did ch...

Phonon dispersion with VASP

Hi
Can we calculate and draw Phonon spectrum/dispersion of a 2D material with VASP alone, without using Phonopy? Because i am always getting negative frequency for a material, but for the same material the correct (or no negative frequency) phonon spectrum is obtained using Quantum Espresso.

Re: Atomic boundary trace or contours in a slice of a super-cell

Dr Graeme, sorry for troubling you. May be i could not ask in clear terminology. 1. First thing i am asking about update of code as per your reply to my query dated - Fri Jan 24, 2020 7:23 pm. To which you replied on Sat Jan 25, 2020 3:51 am. that "....I thought was the larger question about ho...

Re: Atomic boundary trace or contours in a slice of a super-cell

Dr Graeme,

could anything done on this issue to update the code? i am waiting for this please.

Or please tell me if there is any alternative to calculate and draw contours for Zero flux region in the crystal-hybrid for the selected atoms (to form a plane in crystal)

Re: Atomic boundary trace or contours in a slice of a super-cell

Dear Dr Graeme sorry to say, what i asked was different. the 'sel_bader' or 'sel_atom' tags are not working as expected. If i use the command bader-v1-0 CHGCAR -ref CHGCAR_sum -p sel_bader 1-3 its giving the output file as 147940795 Jan 24 18:53 '(@'$'\323\002' If i use bader CHGCAR -ref CHGCAR_sum ...

Re: Atomic boundary trace or contours in a slice of a super-cell

Dear Dr Graeme 1. i run the command as bader -p sel_bader 1-3 CHGCAR -ref CHGCAR_sum generated the files as below. And not able to open them, neither able to change its name. 147940795 Jan 22 18:34 '('$'\020''>'$'\001' 4524 Jan 22 18:34 ACF.dat 113895 Jan 22 18:34 AVF.dat 1670777 Jan 22 18:34 BCF.da...

Re: Atomic boundary trace or contours in a slice of a super-cell

Thank you Dr Graeme. This is quite interesting. 1. Referring to your reply " you can load this file in a viewer and set your min and max contour values to only include the number 1." When a checked the resulted file from the command 'bader -p atom_index CHGCAR -ref CHGCAR_sum' i.e this 'At...

Re: Atomic boundary trace or contours in a slice of a super-cell

Thank you Dr Graeme. My query regarding B and C are summarised as below: May I know how the data in the output file you mentioned as "....a CHGCAR-like file with an integer indicating the locations of the atomic volumes..."? As i wish to draw the 3D contour plot (for only a part of the cry...

Atomic boundary trace or contours in a slice of a super-cell

HI can any one help how to do the following? 1. I have a hybrid supercell strucuture. I have done bader files written ACF, BVF and Atomic volumes files. Also did '-p atom_index' tag with "CHGCAR -ref CHGCAR_sum". What i wish to plot is the 3D picture view of Bader volume boundaries, where ...

Re: Bader Charge analysis

Dr. Graeme,

How are the following analysis commands vary computationally?

$ bader CHGCAR -ref CHGCAR_sum

and

$ bader -b weight CHGCAR -ref CHGCAR_sum
