number_concentration(sys::ParticleSystem) -> Float64

Zeroth moment: n₀ = Nsim / Vcomp [particles/m³].

mass_concentration(u, ::Val{A}, sys) -> Float64

First moment: total mass concentration = (Σᵢ Σₖ μₖᵢ) / V_comp [kg/m³].

species_mass_concentration(u, species_idx, ::Val{A}, sys) -> Float64

Mass concentration of a single species: (Σᵢ μ{speciesidx,i}) / V_comp.
