Member Function Documentation

execute()

void openswmm::runoff::RunoffSolver::execute	(	SimulationContext &	ctx,
		double	dt,
		double	evap_rate = 0.0,
		double	infil_factor = 1.0,
		double	recovery_factor = 1.0,
		int	month = -1
	)

Parameters

infil_factor	Monthly infiltration rate multiplier (default 1.0).
recovery_factor	Monthly soil recovery multiplier (default 1.0).

Here is the call graph for this function:

infil_get_state()

void openswmm::runoff::RunoffSolver::infil_get_state ( int  i, int &  model, double  state[6]  ) const

noexcept

Pack infiltration state for subcatchment i into a flat 6-element array.

Layout (matches legacy infil_getState() encoding):

• Horton/ModHorton (0,1): [tp, Fe, Fmh, 0, 0, 0]
• GA/ModGA (2,3): [IMD, F, Fu, T, sat(0/1), 0]
• CurveNum (4): [S, Se, P, F, f, T]

Parameters

i	Subcatchment index.
model	[out] InfilModel enum value.
state	[out] 6-element flat state array.

Here is the caller graph for this function:

infil_set_state()

void openswmm::runoff::RunoffSolver::infil_set_state ( int  i, int  model, const double  state[6]  )

noexcept

Restore infiltration state for subcatchment i from a flat 6-element array.

Only updates the state fields; does not reinitialise parameters. Silently ignores out-of-range i or mismatched model type.

Parameters

i	Subcatchment index.
model	InfilModel enum value stored in the hot start file.
state	6-element flat state array written by infil_get_state().

Here is the caller graph for this function:
