(2016-07-27)We present a new family of discrete-ordinates (Sn) angular quadratures based on discontinuous finite elements (DFEM) in angle. The angular domain is divided into spherical quadrilaterals (SQs) on the unit sphere surface. ...

(2010-01-16)In this dissertation, we develop Adaptive Mesh Refinement (AMR) techniques for the steady-state multigroup SN neutron transport equation using a higher-order Discontinuous Galerkin Finite Element Method (DGFEM). We propose ...

(2012-07-16)Preconditioners based upon sweeps and diffusion-synthetic acceleration (DSA) have been constructed and applied to the zeroth and first spatial moments of the 1-D transport equation using SN angular discretization and a ...
