An Adaptive Mesh Refinement (AMR) technique is presented for the one-group and the multigroup SNtransport equations discretized using a Discontinuous Galerkin (DG) method. A diffusion synthetic accelerator, also based on a DG discretization and directly obtained from the discretized transport equations, is given. Numerical results are provided for 2D unstructured triangular meshes. © Società Italiana di Fisica.
