Struct SpringMassSystem 

pub struct SpringMassSystem {
    pub masses: Vec<f32>,
    pub springs: Vec<Spring>,
}

Simple 1D spring-mass system supporting Verlet integration.

Positions and velocities are 1D arrays of length n_masses.

Fields

masses: Vec<f32>

springs: Vec<Spring>

Implementations

impl SpringMassSystem

pub fn new( masses: Vec<f32>, springs: Vec<(usize, usize, f32, f32)>, ) -> Result<Self, SimError>

Create a spring-mass system.

pub fn simulate_step( &self, positions: &[f32], velocities: &[f32], dt: f32, ) -> Result<(Vec<f32>, Vec<f32>), SimError>

Velocity Verlet integration step. Returns (new_positions, new_velocities).

pub fn kinetic_energy(&self, velocities: &[f32]) -> f32

KE = Σ 0.5 mᵢ vᵢ²

pub fn potential_energy(&self, positions: &[f32]) -> f32

PE = Σ springs 0.5 k (|x_j - x_i| - rest_length)²
