CentralDiffDerivation Derived Type

type, public, extends(Derivation) :: CentralDiffDerivation

Returns equal to the central difference of the first passed (fluid) variable, optionally multiplied by a constant and product of fluid variables raised to corresponding powers


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(:) :: varPowers

Powers corresponding to each fluid variable - indices in calculate must conform to size of this + 1
real(kind=rk), private :: multConst

Multiplicative constant - default 1
real(kind=rk), private, allocatable, dimension(:) :: leftMult
real(kind=rk), private, allocatable, dimension(:) :: centralMult
real(kind=rk), private, allocatable, dimension(:) :: rightMult
