# IncompressibleNavierStokes.get_lims — Function.

get_lims(x) -> Tuple{Any, Any}
get_lims(x, n) -> Tuple{Any, Any}

Get approximate lower and upper limits of a field x based on the mean and standard deviation ($\mu \pm n\sigma$). If x is constant, a margin of 1e-4 is enforced. This is required for contour plotting functions that require a certain range.

get_spectrum(
    setup;
    npoint,
    a
) -> NamedTuple{(:κ, :masks, :K), <:Tuple{Any, Any, Any}}

Get energy spectrum of velocity field.

# IncompressibleNavierStokes.plotgrid — Function.

plotgrid(x, y; kwargs...)
plotgrid(x, y, z)

Plot nonuniform Cartesian grid.

# IncompressibleNavierStokes.spectral_stuff — Method.

spectral_stuff(
    setup;
    npoint,
    a
) -> NamedTuple{(:A, :κ, :K), <:Tuple{Any, Any, Any}}

Get utilities to compute energy spectrum.
