Left: radial gas temperature profile in the mid-plane of the disk following the test of Pinte et al. (2009). Right: vertical gas temperature profile at a cylindrical radius of 0.2 AU in the disk. We compare the gas temperature computed using  RADMC-3D, the hybrid method (M1+FLD) and the FLD method alone in RAMSES. The integrated optical depth in the disk mid-plane is τ_{810 nm} = 10³ and the stellar temperature is T_⋆ = 4000 K.
