Description

Nodal method based on both symmetry properties of a 3-D hexagon and an analytical representation of the node flux distribution is presented. The only approximations used in deriving the basic relations for the simplest version of the method are node coupling by surface averaged partial currents and eight unknown constants in the node flux representation per group. An experimental code HEXZ has been developed to estimate the accuracy of the method. Numerical results for various 2-D and 3-D benchmarks are presented alongside with some auxiliary finite-difference and nodal ones. (author)
