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]).

	Compute edge fluxes for all triangles.
void	openswmm::twoD::assembleRHS (const MeshData &mesh, const SurfaceStateData &state, const SolverOptions2D &opts, double *ydot)
	Assemble the RHS of the ODE system: dψ/dt for each triangle.
void	openswmm::twoD::assembleImplicitRHS (const MeshData &mesh, const SurfaceStateData &state, const SolverOptions2D &opts, double *ydot)
