Resumo
A new approach for the development of a coarse-mesh numerical spectral nodal method is presented in
this paper. This method, referred to as the Spectral Deterministic Method { Constant Nodal (SDM{CN),
is based on a spectral analysis of the multigroup X,Y-Geometry, linearly anisotropic scattering neutron
transport equations in discrete ordinates ( SN)formulation for xed-source calculations in non-multiplying
media. In this paper we present typical model problems to illustrate the accuracy and the e ciency for
coarse-mesh energy multigroup SN calculations of the SDM-CN method. The numerical results obtained
are compared with the traditional ne-mesh Diamond Di erence (DD) method and the results obtained
by DOT{II and TWOTRAN codes. The numerical results are also compared with the spectral nodal
method, spectral Green's function (SGF).
