Solution profiles of the scalar flux for various methods

The discrete ordinates discontinuous Galerkin (SN -DG) method is a well-established and practical approach for solving the radiative transport equation. In this paper, we study a low- memory…

Numerical errrors from simulation of a radiating sphere.

In this paper, two modifications are introduced for improving the accuracy, versatility, and robustness of a class of hybrid methods for radiation transport.  Such ethods are constructed by…

Comparison of several iterative solvers for multiscale simulations of a silicon diode. The implicit solvers are faster than standard explicit (EX) or implicit-explicit (IMEX) schemes. The reduced-order preconditioner gives another 50% speedup.

Researchers from Oak Ridge National Laboratory and the University of Massachusetts Dartmouth investigated several different approaches for solving fully implicit discretizations of a simplified…

Steady state free electron distribution of a silicon diode model with a bias voltage.

Several different approaches are proposed for solving fully implicit discretizations of a simplified Boltzmann-Poisson system with a linear relaxation-type collision kernel.  This system models…
