Hi
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 charge density difference subtracting from say, Optimised CHGCAR minus non-optimised CHGCAR, giving raise to another similar formatted CHGDIFF.vasp file.
Now, i wish to create a 2D plot to show the integrated values of charge along z-direction.
assuming the option '315' in vaspkit, i run the option, gave input of this CHGDIFF.vasp and asked two values in 'a' and 'b' directions. not clear what these values for, i gave '1 and 1'.
Then it gave three .grd format files. I could not open these files in vesta. when i try the VESTA is shutting down. These files cant be opened in Material studio also.
Can anyone help to understand How to do such integration either with vaspkit or otherwise 'numerically'.?
