## Keyword descriptions

CUTOFF: real = -2.00000000E+000 [Ry]

  Usage: CUTOFF 300

  The cutoff of the FFT grid used in the calculation of the nonlocal vdW functional [Ry]. [Edit on GitHub]

KERNEL_FILE_NAME: string = vdW_kernel_table.dat

  Usage: KERNEL_FILE_NAME <FILENAME>

  Name of the kernel data file, may include a path. vdW_kernel_table.dat is for DRSLL and LMKLL and rVV10_kernel_table.dat is for rVV10. [Edit on GitHub]

PARAMETERS: real[2] = 6.30000000E+000 9.30000000E-003

  Usage: PARAMETERS 6.3 0.0093

  Parameters b and C of the rVV10 functional [Edit on GitHub]

SCALE: real = 1.00000000E+000

  Usage: SCALE 1.0

  Scales the energy contribution of the rVV10 functional [Edit on GitHub]

TYPE: enum = DRSLL

  Usage: TYPE DRSLL

  Valid values:

  - `DRSLL` Dion-Rydberg-Schroeder-Langreth-Lundqvist nonlocal van der Waals density functional

  - `LMKLL` Lee-Murray-Kong-Lundqvist-Langreth nonlocal van der Waals density functional

  - `RVV10` Revised Vydrov-van Voorhis nonlocal van der Waals density functional

  References: Tran2013

  Type of functional (the corresponding kernel data file should be selected). Allows for common forms such as vdW-DF, vdW-DF2, optB88-vdW, rVV10. [Edit on GitHub]

VERBOSE_OUTPUT: logical = F

  Lone keyword: `T`

  Usage: VERBOSE_OUTPUT

  Extensive output for non local functionals [Edit on GitHub]
