Utilization of Chebyshev technique in the FEM nodal method

Description

We have developed a computer code that employs the nodal flux expansion method (FEM) in order to calculate the eigenvalue and the neutron flux for two energy groups for bidimensional problems. This microcomputer-oriented code employs also the two-parameter Chebyshev acceleration method for improving the iterative process convergence due to the discretization approach adopted. The results obtained so far demonstrate the applicability of the acceleration technique to the FLUX Expansion Method. (author)
