Interfaces

interface

  • private module subroutine initScalingLBCGen(this, vspaceObj, isActive, fDeriv, fDerivReqIndices, colL, dx, includedDecompHarmonics)

    Scaling logical boundary condition value generator initialization routine

    Arguments

    Type IntentOptional Attributes Name
    class(ScalingLBCStencilGen), intent(inout) :: this
    type(VSpace), intent(in) :: vspaceObj

    VSpace object used to get grid data

    logical, intent(in) :: isActive

    Set to true if the process containing this has a boundary where this is to be applied

    type(FScalingDerivation), intent(in) :: fDeriv

    Derivation used to get scaling factors

    integer(kind=ik), intent(in), dimension(:) :: fDerivReqIndices

    Indices required for scaling extrapolation derivation
    integer(kind=ik), intent(in) :: colL

    Column l harmonic
    real(kind=rk), intent(in) :: dx

    Boundary cell width
    integer(kind=ik), intent(in), optional, dimension(:) :: includedDecompHarmonics

    Harmonics to be included in the decomposition for this generator (useful for right boundary on staggered grid). Defaults to all harmonics.

interface

  • private module subroutine calcScalingLBCVals(this, varCont, res, mbData, hostModel)

    Calculate scaling logical boundary condition values in place

    Arguments

    Type IntentOptional Attributes Name
    class(ScalingLBCStencilGen), intent(inout) :: this
    type(VariableContainer), intent(in) :: varCont
    type(RealArray), intent(inout), allocatable, dimension(:) :: res
    class(ModelboundData), intent(in), optional :: mbData
    class(ModelSurrogate), intent(in), optional :: hostModel

Derived Types

type, public, extends(JaggedArrayGenerator) ::  ScalingLBCStencilGen

JaggedArrayGenerator for calculating logical boundary condition for electron distribution function. Contains x,h,v dependencies. Expects xStencil = [0] or [-1], depending on whether the boundary is left or right, and whether variables are staggered. The hStencil should cover all harmonics and assumes no m>0 harmonics. Expects vStencil = [0,1]. Calculates v*f_{cl}, without taking the x width or boundary sign into account.
