Uses

Interfaces

interface

  • private module subroutine initCValGen(this, partitionObj, procRank, innerJ, outerJ, xPeriodic, staggeredGridMode)

    Central differentiation stencil value generator initialization routine

    Arguments

    Type IntentOptional Attributes Name
    class(CDiffStencilValGenerator), intent(inout) :: this
    type(Partition), intent(in) :: partitionObj

    Partition object used to determine local number of rows
    integer(kind=ik), intent(in) :: procRank

    Current processor rank
    real(kind=rk), intent(in), dimension(:) :: innerJ

    Inner/column jacobian/hodge star (should conform to x-grid)
    real(kind=rk), intent(in), dimension(:) :: outerJ

    Outer/row inverse jacobian/hodge star (should conform to x-grid)
    logical, intent(in), optional :: xPeriodic

    Used to determine if outer processors should have their stencils trimmed. Defaults to .false.
    logical, intent(in), optional :: staggeredGridMode

    If true will remove last row/column if not periodic

interface

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

    Calculate central diff stencil values in place (does not depend on varCont)

    Arguments

    Type IntentOptional Attributes Name
    class(CDiffStencilValGenerator), 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) ::  CDiffStencilValGenerator

JaggedArrayGenerator for calculating fixed central differencing stencil with no face interpolation

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(:) :: innerJ

Inner/column jacobian/hodge star

real(kind=rk), private, allocatable, dimension(:) :: outerJ

Outer/row inverse jacobian/hodge star
logical, private :: periodicGrid

True if stencil is calculated on periodic grid
logical, private :: staggeredGridMode

If true will remove last row/column if not periodic
integer(kind=ik), private :: minX

Local minX (obtained from partition data)
integer(kind=ik), private :: maxX

Local maxX
