Discontinuous finite element methods for the SN equations on three-dimensional unstructured tetrahedral and hexahedral meshes are presented. Solution techniques including source iteration and diffusion-synthetic acceleration are described. Numerical results are presented that demonstrate the accuracy and efficiency of these methods.
