Functions
void	openswmm::twoD::computeUnlimitedGradients (const MeshData &mesh, SurfaceStateData &state, int nthreads=1)
	Compute unlimited gradients for all triangles via Green-Gauss theorem.
void	openswmm::twoD::computeLimitedGradients (const MeshData &mesh, SurfaceStateData &state, double epsilon, int nthreads=1)
	Apply Jawahar-Kamath slope limiter (Eq. [23]–[24]).
void	openswmm::twoD::computeCellContinuity (const MeshData &mesh, SurfaceStateData &state, const SolverOptions2D &opts, double dt)
	Compute the per-cell continuity residual (local mass-balance check).
void	openswmm::twoD::computeFaceVelocity (const MeshData &mesh, SurfaceStateData &state, const SolverOptions2D &opts)
	Reconstruct cell-centred velocity (vx, vy) from edge fluxes (RT0).
double	openswmm::twoD::computeBoundaryEdgeFlux (const MeshData &mesh, const SurfaceStateData &state, const SolverOptions2D &opts, double dh_eps, int i, int idx) noexcept
	Boundary-edge flux for cell i across flat mesh edge slot idx (m³/s, inflow-positive). Exported wrapper over the file-local boundary kernel so non-DW solvers (the explicit marcher) evaluate the identical 5-type boundary math per substep.
OPENSWMM_KERNEL_FN double	openswmm::twoD::faceDepthFromEta (double eta, double z_lo, double z_hi) noexcept
