Struct Rkn6Splitting 

pub struct Rkn6Splitting {
    pub g: f64,
    /* private fields */
}

6th-order symplectic integrator (triple-jump composition of Yoshida).

Higher accuracy than Yoshida alone (4th-order), at the cost of 3x the sub-steps per time step. Useful when very tight energy conservation is required or when large time steps are desirable.

Fields

g: f64

Gravitational constant G used in the Poisson solve.

Implementations

impl Rkn6Splitting

pub fn new(g: f64) -> Self

Creates a 6th-order triple-jump integrator with the given gravitational constant.

Trait Implementations

impl TimeIntegrator for Rkn6Splitting

fn advance( &mut self, repr: &mut dyn PhaseSpaceRepr, solver: &dyn PoissonSolver, advector: &dyn Advector, dt: f64, ) -> Result<StepProducts, CausticError>

Advance the simulation by one timestep Δt.

fn max_dt(&self, repr: &dyn PhaseSpaceRepr, cfl_factor: f64) -> f64

Compute the maximum stable Δt given current state and CFL constraints.

fn last_step_timings(&self) -> Option<&StepTimings>

Return timing breakdown from the most recent advance() call. Default returns None; instrumented integrators override this.

fn set_progress(&mut self, progress: Arc<StepProgress>)

Attach shared progress state for intra-step TUI visibility. Default is a no-op; integrators that support progress override this.

fn suggested_dt(&self) -> Option<f64>

Return a suggested Δt from the adaptive controller (if any). Default returns None; adaptive integrators override this.
