Struct ModalAnalyzer 

pub struct ModalAnalyzer {
    pub num_modes: usize,
    pub max_iter: usize,
    pub tolerance: f64,
}

Simple power-iteration modal analyzer (extracts the dominant modes of K).

This is a proof-of-concept; it uses a deflated power iteration to approximate the lowest num_modes natural frequencies for undamped free vibration (K φ = ω² M φ, with M = I).

Fields

num_modes: usize

Number of modes to extract.

max_iter: usize

Maximum power-iteration steps per mode.

tolerance: f64

Convergence tolerance.

Implementations

impl ModalAnalyzer

pub fn new(num_modes: usize) -> Self

Create an analyzer that extracts up to num_modes modes.

pub fn analyze(&self, mesh: &PyFemMesh) -> Option<ModalAnalysisResult>

Run modal analysis on the assembled mesh.

Returns None if the mesh has no elements.
