Struct Modal Analysis &nbsp; Copy item path

impl ModalAnalysis

pub fn new() -> Self

pub fn eigenvalue_solver(&self) -> &EigenvalueSolver

Borrow the eigenvalue solver configuration.

pub fn eigenvalue_solver_mut(&mut self) -> &mut EigenvalueSolver

Mutably borrow the eigenvalue solver configuration.

pub fn add_mode_shape(&mut self, mode: ModeShape)

Append a computed mode shape to the results.

pub fn mode_shapes(&self) -> &[ModeShape]

Borrow the computed mode shapes.

pub fn modal_parameters(&self) -> &ModalParameters

Borrow the modal parameters.

pub fn modal_parameters_mut(&mut self) -> &mut ModalParameters

Mutably borrow the modal parameters.

pub fn analyze_modal( &mut self, stiffness: &[f64], mass_diag: &[f64], num_dofs: usize, ) -> Result<Vec<ModeShape>, EngineeringError>

Undamped modal analysis: solves the generalized eigenproblem K φ = ω² M φ for a symmetric stiffness matrix stiffness (row-major num_dofs × num_dofs) and a lumped (diagonal) mass matrix mass_diag (num_dofs positive entries), wired to the crate’s symmetric Jacobi eigensolver via [solve_modal_eigen]. Returns one ModeShape per DOF, ordered by ascending natural angular frequency ω (rad/s) (stored in ModeShape::natural_frequency), with zero damping (undamped) and the mass-normalized mode-shape vector (unit maximum component). The result is also cached in self.mode_shapes.
