Cosmological Strang splitting with scale-factor-dependent coefficients.

Fields

g: f64

scale_factor: f64

Current scale factor a(t).

hubble: f64

Hubble parameter H(t).

omega_m: f64

Matter density parameter Omega_m.

Implementations

impl CosmologicalStrangSplitting

pub fn new(g: f64, scale_factor: f64, hubble: f64, omega_m: f64) -> Self

pub fn set_cosmology(&mut self, scale_factor: f64, hubble: f64)

Update the scale factor and Hubble parameter for the current time.

Trait Implementations

impl TimeIntegrator for CosmologicalStrangSplitting

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.
