Struct PseudospectralMethod 

pub struct PseudospectralMethod {
    pub grid_type: String,
    pub num_modes: usize,
}

Pseudospectral collocation method.

Fields

grid_type: String

Type of collocation grid (“chebyshev”, “legendre”, “fourier”, …).

num_modes: usize

Number of collocation modes.

Implementations

impl PseudospectralMethod

pub fn new(grid_type: impl Into<String>, num_modes: usize) -> Self

Create a new PseudospectralMethod.

pub fn aliasing_condition(&self) -> usize

Aliasing condition: the 2/3-rule requires N_phys ≥ (3/2) N_modes.

pub fn dealiasing_rule(&self) -> usize

Recommended dealiasing padding (number of additional physical points).
