Finite Element Numerical Solution of a Self-Adjoint Transport Equation for Coupled Electron-Photon Problems.

Abstract A novel approach is proposed for charged particle transport problems using a recently developed second-order, self-adjoint angular flux (SAAF) form of the Boltzmann transport equation with continuous slowing down (CSD). A linear continuous (LC) in space and linear discontinuous (LD) in energy finite element discretization is implemented in the computer code DOET1D: Discrete Ordinates Electron-Photon Transport in 1D. DOET(sub 1D) is a one-dimensional, Cartesian coordinates, multigroup, discrete ordinates code for charged particle transport which employs CEPXS generated cross-sections to incorporate electron and photon transport physics.
