Transformations
The Transformations module includes the definition for a Transformer, and the methods definition for the required discrete Fourier transform, and the fractional and physical grid transformation.
Struct
Main.NavierStokesPropagators.Transformations.Transformer — TypeThe Transformer is an encapsulation of the data required for discrete Fourier transform via the FFTW package, containing the FFT plan and the required data for dealiasing.
Public API
The method parameter are dependent on
tf::Transformer{T}:
the Transformer struct encapsulating the required FFTW abstractions for the discrete Fourier transform.
state::State{T}:
the State{T} struct encapsulating the states of the simulations.
arr::Array{Complex{T},3}:
the array to be transformed
frac_mode::Bool:
true if the FFTW call is applied on a fractional array
dealias_mode::Bool:
true if the 2/3-dealiasing scheme should be appliedMain.NavierStokesPropagators.Transformations.physical2fourier! — Methodphysical2fourier!(tf, state)
