Detailed Description

Routing interface file — coupling between separate SWMM simulations.

An upstream model writes outfall results to a text interface file; a downstream model reads those results as inflow boundary conditions. Temporal interpolation between interface file periods ensures smooth coupling even when the two models use different timesteps.

SoA storage: per-node flows and quality values stored in flat arrays for vectorisable interpolation.
