Abstract :
We show how to pass from the local Bean´s model, assumed to be valid as a behavior law for a homogeneous superconductor, to a model of similar form, valid on a larger space scale. The process, which can be iterated to higher and higher space scales, consists in solving for the fields e and j over a “periodicity cell” with periodic boundary conditions
