Expand description

Runge-Kutta 4th order ODE solver with fixed memory footprint

Fields§

§state: [f64; 4]

Current state vector (fixed size)

§dt: f64

Time step size

§t: f64

Current time

§config: SolverConfig

Solver configuration

§solver_state: SolverState

Solver state

Implementations§

Source§

impl RungeKutta4Static

Source

pub fn new(dt: f64, config: SolverConfig) -> Self

Create new RK4 solver

Source

pub fn integrate<F>( &mut self, f: &F, t0: f64, y0: [f64; 4], t_final: f64, ) -> SolverResult<ODEState>
where F: ODEFunction,

Integrate ODE from t0 to t_final

Source

pub fn integrate_until_steady_state<F>( &mut self, f: &F, t0: f64, y0: [f64; 4], t_limit: f64, ) -> SolverResult<ODEState>
where F: ODEFunction,

Integrate until the derivative infinity norm is below the configured tolerance. Unlike Self::integrate, this operation is explicitly a steady-state search and may terminate before t_limit.

Source

pub fn get_state(&self) -> ODEState

Get current state
