Convert CHGCAR to the cube form, you can view it by vesta

You can try the AIM-UC software (https://facyt-quimicomp.neocities.org/Vega_en.html). Any questions about its use, you can consult me.

You can try to change the name of the file from CHGCAR to CHGCAR.vasp

@Van An Dinh I converted vasp file to cube format file by using c2x. But did not work.

I got

"Unhandled unknown exception; terminating the application.

Aborted (core dumped)"

error message

@Sinhué López I also tried by changing the name of file from CHGCAR to CHGCAR.vasp. Again Vesta window gets grey.

Could you upload the CHGCARfile?
