Résumé

We présent the results of Couplex benchmarks for the simulation of radionuclide transport around a nuclear waste repository. They are obtained with a finite-element-finite volume code where the difFusive terms (flow and transport) are discretised with finite élément method and the convective terni with the Godunov type FV method. Calculations are made on structured meshes that fulfil Delaunay and cotangents criteria. Some comparisons between mono- and multi-domain calculations are also included.
