Struct BeamSolver 

pub struct BeamSolver { /* private fields */ }

Beam solver — joint equilibrium via Newton-Raphson in R^{4(N-1)}

Implementations

impl BeamSolver

pub fn new(tolerance: f64) -> Self

pub fn solve(&self, beam: &MultiSegmentBeam) -> Result<JointEquilibrium, String>

Solve joint equilibrium for a multi-segment beam

Algorithm:

1. Initialize joint state guesses (zero internal forces)
2. For each segment, integrate Euler elastica via shooting
3. Collect residuals at each joint: R_j = state_left - state_right
4. Newton-Raphson step in R^{4(N-1)}
5. Iterate until ||R||₂ < tolerance or max iterations

This is O(N) in segment count — each iteration is one forward pass.
