Detailed Description

template<typename Eval>
struct SpeciesSlotFunctor< Eval >

Species fluxes by mass-flux upwinding (Larrouturou 1991), F_k = max(mdot, 0) Y_k^L + min(mdot, 0) Y_k^R, split by the side each part comes from: each cell writes, for each of its faces, the mass of each species leaving it through that face, slot(face, side, k) = A/2 sum_q w_q max(mdot_out, 0) Y_k(q), with Y_k from its own reconstruction (the evaluator Eval, see ScalarFaceValues); boundary faces also get the inflow from the exterior state in slot(face, 1, k). No two threads write the same slot.

With face mass fractions in [0, 1] summing to one, the species fluxes sum to the mass flux and keep rho Y_k non-negative under the flow's CFL limit.
