CASTRO: A New Compressible Astrophysical Solver. III. Multigroup Radiation Hydrodynamics

By weichen zhang and others
We present a formulation for multigroup radiation hydrodynamics that is correct to order O(v/c) using the comoving-frame approach and the flux-limited diffusion approximation. We describe a numerical algorithm for solving the system, implemented in the compressible astrophysics code, CASTRO. CASTRO uses an Eulerian grid with block-structured adaptive mesh refinement based... Show more
