buildOutfallLinkMap()

void openswmm::outfall::buildOutfallLinkMap

(

SimulationContext &

ctx

)

Precompute outfall → connecting-conduit index map.

Walks the link table once at init and, for every outfall node, records the first conduit whose node2 (or node1) is that outfall, together with its offset at the outfall end. Results are stored in ctx.outfall_link_idx / outfall_link_offset so that setAllOutfallDepths can skip the O(N_links) inner scan per Picard iteration.

Parameters

ctx	Simulation context (populates outfall_link_idx / offset).

setAllOutfallDepths()

void openswmm::outfall::setAllOutfallDepths	(	SimulationContext &	ctx,
		double	current_time
	)

Compute boundary depth at all outfall nodes.

For each outfall:

• FREE: critical depth from downstream conduit
• NORMAL: normal depth from downstream conduit
• FIXED: specified water surface elevation
• TIDAL: elevation from tidal curve at current time
• TIMESERIES: elevation from timeseries at current time

Parameters

ctx	Simulation context.
current_time	Current simulation time (decimal days).
