CDiffStencilValGenerator Derived Type

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
