Struct SolverDiagnostics 

pub struct SolverDiagnostics {
    pub iterations: usize,
    pub final_residual: f64,
    pub converged: bool,
    pub history: Vec<f64>,
}

Tracks solver convergence history and diagnostics.

Fields

iterations: usize

Number of iterations performed.

final_residual: f64

Final residual after last iteration.

converged: bool

Whether the solver converged.

history: Vec<f64>

Per-iteration residual history.

Implementations

impl SolverDiagnostics

pub fn new() -> Self

Creates a new, empty SolverDiagnostics.

pub fn record(&mut self, residual: f64)

Records a residual for the current iteration.

pub fn check_convergence(&self, tolerance: f64) -> PhysicsResult<()>

Marks convergence and returns Ok(()), or Err(ConvergenceFailed).

pub fn convergence_rate(&self) -> Option<f64>

Returns the geometric-mean convergence rate from the last 5 residuals, or None if fewer than 2 residuals have been recorded.

pub fn is_diverging(&self) -> bool

Check if the solver is diverging (residual increasing over the last few iterations).

pub fn summary(&self) -> String

Returns a summary string for diagnostics output.

pub fn reset(&mut self)

Reset the diagnostics for a new solve.

impl Default for SolverDiagnostics

fn default() -> Self

Returns the “default value” for a type.
