buildCustomTables()

void openswmm::transect::buildCustomTables	(	TransectData &	td,
		double	y_full,
		const double *	curve_x,
		const double *	curve_y,
		int	n_pts
	)

Build tabulated geometry from a CUSTOM shape curve.

The shape curve defines normalized (y/yFull) vs (width/wMax). This function integrates area and computes hyd-radius tables that can be used by XSectBatch's per-link lookup kernel.

Parameters

td	[out] TransectData to populate (tables and full properties).
y_full	Full depth of the cross-section.
curve_x	Normalized depth values (y/yFull) from shape curve.
curve_y	Normalized width values (w/wMax) from shape curve.
n_pts	Number of curve points.

buildTables()

void openswmm::transect::buildTables

(

TransectData &

td

)

Build tabulated geometry from station-elevation data.

Computes area, hydraulic radius, and width at each of N_TRANSECT_TBL equal depth increments from thalweg to maximum depth, then normalizes.

Parameters

td	[in/out] TransectData with stations/elevations filled. On output, tables and full-depth properties are set.
