Dear Users,
I have a confusion about adding van der waal's grimme correction
to my system. In my system I have put a adsorbate layer on top of a
substrate, the distance of separation is around 4 angstrom but when I add
vdw correction the separation decreases to 3.2 angstrom. With inclusion of
only vdW interaction, I got the separation and the adsorption energy.
However, I need to add Grimme D2 type vdW correction. Do I need to write
input_dft='vdw-DF'
vdw_corr = 'Grimme-D2'
or only the correction: vdw_corr= 'Grimme-D2' without mention input dft.
I am attaching the input file. Please, let me know correction inclusion of
grimme vdW correction. This varition leads to differnt separation as well
as adsorption energy.
Thanks and regards,
