ReferenceImplicitTimeBackend

eqiora::time

Struct ReferenceImplicitTimeBackend 

pub struct ReferenceImplicitTimeBackend;
Description

Small deterministic implicit-Euler/Newton oracle for general residuals.

This backend exists to falsify the residual/JVP and initialization contracts. It is not an adaptive production DAE solver and does not replace a future IDA adapter.

Implementations§

§

impl ReferenceImplicitTimeBackend

Signature links:§ReferenceImplicitTimeBackend

pub const fn new() -> ReferenceImplicitTimeBackend

Signature links:newReferenceImplicitTimeBackend

Construct the stateless reference oracle.

pub fn initialize( &self, problem: &ImplicitDaeProblem<'_>, plan: &TimePlan, ) -> Result<ImplicitDaeInitialization, Diagnostic>

Signature links:initializeImplicitDaeProblemTimePlanResultImplicitDaeInitializationDiagnostic

Solve or accept a consistent initial (y0, y_dot0) pair.

§Errors

Returns stable plan, callback, singular-Jacobian, or nonlinear convergence diagnostics.

pub fn solve( &self, problem: &ImplicitDaeProblem<'_>, plan: &TimePlan, ) -> Result<TimeSolution, Diagnostic>

Signature links:solveImplicitDaeProblemTimePlanResultTimeSolutionDiagnostic

Integrate one residual-native problem with deterministic BDF1 steps.

TimePlan::initial_step is the maximum internal BDF1 step; steps are shortened to land exactly on requested output times.

§Errors

Returns stable admission, callback, singular-Jacobian, or nonlinear convergence diagnostics.
