DFTD4_XC

DFTD4_XC = [string]
Default: DFTD4_XC = The functional set by the GGA, METAGGA or XC tag.

Description: DFTD4_XC sets the exchange-correlation functional which determines the van der Waals parameters used in the DFT-D4 method implemented in the DFT-D4 package.

DFTD4_XC allows to choose the exchange-correlation functional that determines which set of van der Waals parameters is used in the DFT-D4 method implemented in the DFT-D4 package (IVDW=13).

The possible choices (e.g., DFTD4_XC=pbe, hse06, ...) are listed in the file param.f90 of the DFT-D4 source code.

Mind:

The DFTD4_XC tag is available from VASP.6.6.0 onwards.
The DFTD4_XC tag can be used only for the DFT-D4 package (IVDW=13).
