“…In contrast, the Finite Volume Method (FVM) is easily applied to unstructured meshes. In addition, the application of the FVM to the NDE is feasible, as discussed by Bernal et al [5,6] and Theler [7].…”

“…In this paper, the FVM based on a polynomial expansion method [6] has been used to discretize the steady state of the NDE to obtain the matrices of the eigenvalue problem. This eigenvalue problem has been solved by means of the SLEPc library, which is appropriate to solve eigenvalue problems in which the associated matrices are sparse, such as those arising after the discretization of partial differential equations [8,9].…”

“…A quarter of horizontal and one half of vertical cross section of the 3D-IAEA problem are illustrated in Figures 1 and 2, respectively. The multi-group neutron diffusion approximation that most widely used for commercial reactors is the two-energy groups approximation [37,38], which is also applied in 3D-IAEA benchmark problem. The neutron energy spectrum is divided into two groups, which are called fast and thermal neutrons, respectively.…”

“…Los métodos basados en los elementos finitos (FEM) [20] [21] y en volúmenes finitos (FVM) [19] compiten directamente ya que ambos pueden ser utilizados con gran flexibilidad adaptándose a distintas formas y tamaños de malla. La ventaja principal de estos métodos de integración espacial es que puede ajustarse con precisión a cualquier geometría complicada (flexibilidad geométrica) a costa de incrementar la dimensión del problema.…”
