absorbTreatedNodeConc()

void openswmm::transport::ArdEngine::absorbTreatedNodeConc

(

SimulationContext &

ctx

)

E5b treatment interop: absorb treated node concentrations back into the node stores.

Called by SWMMEngine AFTER QualitySolver::applyTreatment ran on the PUBLISHED nodes.conc. Only nodes with treatment defined are touched — untreated nodes keep their store mass bit-identical (a conc→mass→conc round trip is NOT exact in floating point, so a blanket absorb would break the no-treatment parity).

Here is the call graph for this function:

Here is the caller graph for this function:

init()

bool openswmm::transport::ArdEngine::init

(

SimulationContext &

ctx

)

Build the transport mesh and size all state; call once after the model is fully resolved (Router::init done, pollutants known).

Returns

false if the mesh could not be built — the caller must fall back to the legacy quality path and surface the warnings.

Here is the call graph for this function:

initialized()

bool openswmm::transport::ArdEngine::initialized ( ) const

inlinenoexcept

step()

void openswmm::transport::ArdEngine::step	(	SimulationContext &	ctx,
		double	dt )

One transport step over the routing step dt.

Pre-condition: the external quality loads for this step have been assembled into nodes.qual_mass_in / qual_vol_in (the QualitySolver loader stage). Post-condition: links.conc, links.conc_old, nodes.conc, nodes.conc_old updated.

Here is the call graph for this function:

Here is the caller graph for this function:

totalMass()

std::vector< double > openswmm::transport::ArdEngine::totalMass

(

const SimulationContext &

ctx

)

const

Total species mass currently held (cells + node stores), one entry per species — the conservation ledger the unit gates check.

Here is the call graph for this function:

Here is the caller graph for this function:

warnings()

const std::vector< std::string > & openswmm::transport::ArdEngine::warnings ( ) const
