3. DESCRIPTION OF PROGRAM OR FUNCTION

MARCOPOLO calculates the radial and axial diffusion coefficients in one-group and multi-group theory for a cylidrisized cell (Wigner-Seitz theory) with several concentric zones according to the isotropic shock or linear anisotropic shock hypotheses. The diffusion coefficients are calculated with zero radial and axial Laplacian.
