	Live node-coupling orifice flux for ONE non-outfall coupling point.
double	openswmm::twoD::computeNodeCouplingDQdh1d (const CouplingPoint &cp, const MeshData &mesh, const SurfaceStateData &state, const NodeData &nodes, const SolverOptions2D &opts) noexcept
	Head sensitivity G = −∂Q/∂h_1d ≥ 0 of the coupling orifice at a point (SI: m³/s per m of 1D head, with h_1d in 2D metres).
