Struct SpectralElementMethod 

pub struct SpectralElementMethod {
    pub num_elements: usize,
    pub poly_degree: usize,
}

Spectral element method (SEM) on a 1-D mesh.

Fields

num_elements: usize

Number of non-overlapping elements.

poly_degree: usize

Polynomial degree within each element.

Implementations

impl SpectralElementMethod

pub fn new(num_elements: usize, poly_degree: usize) -> Self

Create a new SpectralElementMethod.

pub fn local_stiffness(&self) -> Vec<Vec<f64>>

Local stiffness matrix for one reference element (size p+1 × p+1).

Uses the Gauss-Lobatto nodes for the quadrature.

pub fn assembly(&self) -> usize

Global assembly: concatenate local stiffness with continuity constraints.

Returns the global stiffness matrix dimension (DOF count).
