Public Member Functions
void	init (int n_conduits, const XSectGroups &groups)
	Initialise for n conduit-type links. Call once after model is built.
int	execute (SimulationContext &ctx, double dt)
	Route all conduits for one KW timestep.

Detailed Description

Kinematic wave solver state.

Holds SoA working arrays for all conduits. Allocated once at init. The execute() method routes all conduits for one timestep.

Member Function Documentation

execute()

int openswmm::kinwave::KWSolver::execute	(	SimulationContext &	ctx,
		double	dt
	)

Route all conduits for one KW timestep.

1. Batch-compute inlet section factors from inflows using XSectGroups
2. For each conduit, solve the Newton continuity equation
3. Batch-compute outflows from outlet section factors
4. Update state arrays

Parameters

ctx	Simulation context (links/nodes modified in place).
dt	Timestep (seconds).

Returns

Average number of Newton iterations across all conduits.
