Coupled radiation hydrodynamics. These numerical profiles have no supplied analytic reference or accuracy norms.
32³ cells; t=7500 s
First-order mixed-frame gas/radiation evolution with physical light speed. Derived lab-frame flux includes radiation enthalpy advection. No independent analytic or digitized reference profile is supplied; M1 differences are model discrepancies.
Mixed-frame FLD with first-order gas transport and backward-Euler diffusion/material exchange; physical c = 29979245800 cm/s. Radiation flux is the derived lab-frame diffusion plus enthalpy-advection flux; it is not an independently evolved momentum variable. No independent analytic or digitized FLD reference profile is supplied. M1 versus FLD differences compare distinct radiation models and are not analytic-reference errors.
Central cell layer at z=dx/2; ray at y=z=dx/2.
