A strictly positive spatial discretization method for the linear transport equation is presented. This method, which is algebraically nonlinear, enforces particle conservation on subcells and… (More)
Radiative transfer problems of practical interest often contain regions that are extremely optically thick and highly diffusive. In multidimensional problems, memory and CPU limitations force the use… (More)
We present here a nonlinear corner-balance (NLCB) method for spatially discretizing the discrete ordinates transport equation. We describe the method in slab and X-Y geometries and give numerical… (More)
