+For static diffusion, the terms in blue with v^2^/c can be dropped and the system can be split into the usual hydro update (black), radiative source terms (green), and a coupled implicit solve (red) for the radiation energy density and thermal energy density (ie temperature). And the terms in orange can be solved semi-implicitly (velocity terms are explicit, while radiation energy terms are implicit)
