    logical, intent(in), optional :: leftBoundary

    True if extrapolating to left boundary. Defaults to false.
    logical, intent(in), optional :: staggeredVars

    True if the distribution has staggered harmonics. Defaults to false.

    True if the extrapolation should be performed to the cell boundary and not the last cell centre before the boundary.

Derived Types

type, public, extends(MatDerivation) ::  FScalingDerivation

Extrapolates a distribution function to the boundary or last cell centre as a (numH,numV) matrix. Assumes that there are no m>0 harmonics for staggered grids. Expects 1-4 variables. The first is the extrapolated distribution, the second the density vector. The third is the staggered density if the variables are staggered. The value of the density at the boundary (scalar) is either the third or the fourth variable, and should be present only if extrapolating to the boundary.

Components

Type Visibility Attributes Name Initial
logical, public :: userDefined = .false.

True only if user explicitly sets it to true
integer(kind=ik), public, dimension(2) :: exterpCoords

Coordinates used for extrapolation. Should be the indices of the cells closest to the boundary on the regular and dual grids, respectively.
logical, private :: hasBoundary

True if the processor this derivation is calculated on has the corresponding external boundary. If it doesn't, this derivation returns 0.
logical, private :: leftBoundary
integer(kind=ik), private :: numV

Number of velocity grid points
integer(kind=ik), private :: numH

Number of harmonics
logical, private :: staggeredVars

True if the distribution has staggered harmonics. Defaults to false.
logical, private :: extrapolateToBoundary

True if the extrapolation should be performed to the cell boundary and not the last cell centre before the boundary.
