## Keyword descriptions

FREQUENCY: real = 0.00000000E+000 [s^-1]

  Usage: FREQUENCY <real>

  The frequency with which the oscillating fraction oscillates. [Edit on GitHub]

N_PRTN: integer[3] = 1 1 1

  Usage: N_PRTN <integer> <integer> <integer>

  The number of partitions in the x, y and z directions for partitioning the cuboid. [Edit on GitHub]

OSCILLATING_FRACTION: real = 0.00000000E+000

  Usage: OSCILLATING_FRACTION <real>

  A fraction of the field can be set to oscilate over time. [Edit on GitHub]

PERIODIC_REGION: logical = F

  Lone keyword: `T`

  Usage: PERIODIC_REGION <logical>

  Whether or not to take into consideration the effects of the periodicity of the simulation cell (MIXED_PERIODIC bc) for regions defined sufficiently close to the boundaries. [Edit on GitHub]

PHASE: real = 0.00000000E+000

  Usage: PHASE <real>

  The phase of the oscillattion. A phase of zero corresponds to a cosine function. [Edit on GitHub]

SMOOTHING_WIDTH: real = 2.00000000E-001 [angstrom]

  Aliases: SIGMA

  Usage: SMOOTHING_WIDTH <real>

  The width of the transition region between the Dirichlet subdomain and its surrounding. [Edit on GitHub]

V_D: real = [volt]

  Usage: v_D <real>

  The value of the fixed potential to be imposed at the region. [Edit on GitHub]

X_XTNT: real[2] = [angstrom]

  Usage: X_xtnt <xmin(real)> <xmax(real)>

  The X extents of the cuboid. [Edit on GitHub]

Y_XTNT: real[2] = [angstrom]

  Usage: Y_xtnt <ymin(real)> <ymax(real)>

  The Y extents of the cuboid. [Edit on GitHub]

Z_XTNT: real[2] = [angstrom]

  Usage: Z_xtnt <zmin(real)> <zmax(real)>

  The Z extents of the cuboid. [Edit on GitHub]
