High-Order Mixed Finite Element Discretization for the Variable Eddington Factor Equations
Samuel Olivier, University of California, Berkeley
This paper presents a multi-dimensional, high-order, mixed finite element discretization for the variable Eddington factor equations coupled to an upwind discontinuous Galerkin discrete ordinates discretization. The resulting acceleration scheme is shown to maintain the order of accuracy of the discrete ordinates discretization in isolation, accelerate source iteration and preserve the thick diffusion limit.
