Two new mixed finite element schemes for discretizing current continuity equations are presented. Together with the good features of the already-known mixed scheme (current preservation and good approximation of sharp shapes), they provide M-matrices, even when a zero order term is present in the equations.

Abstract
Two new mixed finite element schemes for discretizing current continuity equations are presented. Together with the good features of the already-known mixed scheme (current preservation and good approximation of sharp shapes), they provide M-matrices, even when a zero order term is present in the equations.File in questo prodotto:
