Functions
double	openswmm::node::getVolume (const NodeData &nodes, int idx, double depth, TableData *tables=nullptr, int unit_sys=0)
	Compute volume at a given depth for a single node.

double	openswmm::node::getSurfArea (const NodeData &nodes, int idx, double depth, TableData *tables=nullptr, int unit_sys=0)
	Compute surface area at a given depth for a single node.

double	openswmm::node::getPondedArea (const NodeData &nodes, int idx, double depth)
	Get the ponded area (for overflow above rim).

double	openswmm::node::getMaxOutflow (const NodeData &nodes, int idx, double q, double dt)
	Compute max outflow limited by available volume.

double	openswmm::node::getOverflow (double new_volume, double full_volume, double dt)
	Compute overflow rate at a node.

double	openswmm::node::getDepth (const NodeData &nodes, int idx, double volume, TableData *tables=nullptr, int unit_sys=0)
	Compute depth from volume for a single node (inverse of getVolume).

double	openswmm::node::getHead (double invert_elev, double depth)
	Compute head from depth: head = invert + depth.

void	openswmm::node::computeHeads (const double invert, const double depth, double *head, int n)
	Compute head = invert + depth for all nodes.

void	openswmm::node::computeVolumes (const NodeData &nodes, const double depth, double volume)
	Compute volumes for all nodes from their current depths.

void	openswmm::node::computeOverflows (const double new_volume, const double full_volume, double *overflow, double dt, int n)
	Compute overflow for all nodes.

Detailed Description

Node hydraulics — volume/depth/head conversions, surface area, overflow.

All functions operate on SoA arrays from NodeData. They are designed for batch operation over all nodes in a single call.
