A new attempt for radiation hydrodynamics simulation with anisotropic and non-equilibrium distribution

We present a computational method for solving time-dependent radiation moment equations with an Eddington tensor which represents an anisotropic field of radiation. For estimating the Eddington tensor, we propose a conical-ray method covering the whole solid angle with which the steady-state radiative transfer equation is solved. Computed radiation flux shows an excellent agreement with an analytical solution using the proposed conical-ray method even if a light source is located at a distant place from the computed point.
