VDW_RADIUS and dftd4.

[hszhao.cn@gmail.com]

Based on the description here:

VDW_RADIUS sets the cutoff radius for the van der Waals pair interactions in Å \AA for the DFT-D2, DFT-D3, DFT-ulg, DDsC, and Tkatchenko-Scheffler methods.

So, does DFTD4 have nothing to do with this parameter?

Dear Zhao,

DFTD4 does not read VDW_RADIUS.
Only following tags are read by the library in VASP:

• VDW_S6
• VDW_S8
• VDW_A1
• VDW_A2
