Struct FdeOptions 

pub struct FdeOptions<S: Scalar> {
    pub dt: S,
    pub max_steps: usize,
    pub tol: S,
    pub max_iter: usize,
}

Options for FDE solvers.

Divergence from numra_ode::SolverOptions (per Foundation Spec §2.5): fractional-order methods shipped here (the L1 scheme) are inherently fixed-step — the Caputo-derivative discretisation writes the convolution memory against a fixed dt grid. Variable-step fractional methods exist in the literature but are not in v1 scope, so rtol / atol-style adaptive step control would be a dead knob. tol and max_iter govern the nonlinear iteration inside implicit schemes (Newton on the convolved residual), not local truncation error — same identifier, different meaning from SolverOptions::atol. See docs/architecture/foundation-specification.md §2.5.

Fields

dt: S

Time step size

max_steps: usize

Maximum number of steps

tol: S

Tolerance for iterative methods (if applicable)

max_iter: usize

Maximum iterations for implicit methods
