[QE-users] Query about optB86b functional

Dear Users,
I want to simulate a carbon based layered materials where I want to
use optB86b functional.

I use:

!  vdw_corr='Grimme-D3',  (optB86b with vdw_corr did not work so I removed
it)
  input_dft='vdW-DF-ob86',

Can someone please confirm whether the regular Pseudopotentials available
on Quantum Espresso Web-Page works  or for optB86b functional I need some
other PPs?


Thank you very much,

Best regards
Rekha
