InterpolationDerivation Derived Type

type, public, extends(Derivation) :: InterpolationDerivation

Derivation that interpolates a variable from the original to the dual grid, or vise versa. Distributions are interpolated by assuming that even l harmonics live on the original grid and odd harmonics on the dual grid.


Components

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

True only if user explicitly sets it to true
real(kind=rk), private, allocatable, dimension(:) :: linInterp

Linear interpolation coefficients for inner points
real(kind=rk), private, allocatable, dimension(:) :: linInterpDual

Linear interpolation coefficients for inner points on dual grid
real(kind=rk), private :: linExterp

Linear extrapolation coefficients for the right boundary point
real(kind=rk), private :: linExterpRDual

Linear extrapolation coefficient for the right boundary point during inverse interpolation on non-periodic grid
real(kind=rk), private :: linExterpLDual

Linear extrapolation coefficient for the left boundary point during inverse interpolation on non-periodic grid
logical, private :: periodicGrid
logical, private :: inverseInterp

True if interpolating from dual to original grid. Defaults to false
logical, private :: distInterp

True if interpolating a distribution function
logical, private :: containsLeftBoundary

True if the local x-grid contains the left boundary
logical, private :: containsRightBoundary

True if the local x-grid contains the right boundary
integer(kind=ik), private :: locNumX

Size of local grid chunk (without any halos)
integer(kind=ik), private :: numV
integer(kind=ik), private :: numH
logical(kind=ik), public, allocatable, dimension(:) :: oddHarmonic

True for odd l harmonics
