addWetWeatherLoads()

void openswmm::quality::QualitySolver::addWetWeatherLoads	(	SimulationContext &	ctx,
		double	dt
	)

Add subcatchment washoff quality loads to node inflows.

For each subcatchment with runoff, adds the washoff concentration × flow as mass inflow to the outlet node. Matches legacy addWetWeatherInflows() in routing.c.

Here is the caller graph for this function:

execute()

void openswmm::quality::QualitySolver::execute	(	SimulationContext &	ctx,
		double	dt
	)

Execute one quality routing timestep.

1. Accumulate link mass flows → node quality (batch over links)
2. Complete mixing at nodes: c_new = (c_old*V + W*dt) / (V + Vin)
3. First-order decay: c = c * (1 - k*dt)
4. Update link quality from upstream node

Parameters

ctx	Simulation context.
dt	Timestep (seconds).

init()

void openswmm::quality::QualitySolver::init	(	int	n_nodes,
		int	n_links,
		int	n_pollutants
