Title: Discontinuous Galerkin Finite Element Method applied
to the 1-D Spherical Neutron Transport Equation


Abstract:
Discontinuous Galerkin finite-element methods are used
to estimate solutions to the 1-D spherical neutron
transport equation.  Various trial and test spaces are
compared in the context of a few sample problems whose
exact solution is known.  Certain trial spaces
avoid unphysical behavior that seem to plague other
methods. Comparisons with diamond differencing and
simple corner-balancing are presented to highlight
these improvements.
