class	openswmm::rdii::RDIISolver
	Mutable strict-grid UH convolution, rainfall queues and node-flow history. Configure validated UH/decay/assignment rows before init. Serialize all access; advance mutates queues, abstraction, optional SWE and context balance totals. Stored float32 grid rows grow for the whole run; no streaming eviction/rollback. Direct public uh_params/decay_params edits require compatible layout and a fresh initialization before reuse. Exceptions can leave partial changes. More...

Functions
double	openswmm::rdii::getRecoveryRate (const ExpDecayParams &dp, double T_celsius)
	Compute exponential-IA additive recovery at one air temperature.

double	openswmm::rdii::updateIA_exp (const UnitHydParams &uh, UHResponseData &rd, const ExpDecayParams &dp, int month, int response, double rainDepth, double dt_sec, const SimulationContext &ctx)
	Update exponential abstraction and optional degree-day SWE for one rain chunk.

Detailed Description

RDII — rainfall-dependent infiltration/inflow via unit hydrograph.

Each RDII node has 3 triangular unit hydrographs (short/medium/long response). The RDII inflow at each timestep is the convolution of past rainfall with the UH ordinates.

SoA: past rainfall stored as circular buffer per UH group. Convolution is a dot-product — vectorisable.
