An Integral Form of the Variational Nodal Method

open access: yesNuclear Science and Engineering, 2004
An integral form of the variational nodal method is formulated, implemented, and tested. The method combines an integral transport treatment of the even-parity flux within the spatial node with an odd-parity spherical harmonics expansion of the Lagrange multipliers at the node interfaces.

Improved Variational Nodal Method Based on Symmetry Group Theory

Nuclear Science and Engineering, 2018
AbstractTo reduce the calculation effort and memory requirement for high-order PN expansion calculation in the Variational Nodal Method (VNM), the surficial irreducible basis functions based on the symmetry group theory have been employed to block-diagonalize one of the four nodal response matrices.
