文摘In this paper, a Galerkin/Petrov-least squares mixed finite element method forthe stationary conduction-convection problems is presented and analyzed. Themethod is consistent ahd stable for any combination of discrete velocity and pres-sure spaces without requiring the Babuska-Brezzi stability condition. The exis-tence, uniqueness and convergence (at optimal rate) of the discrete solution isproved in the case of sufficient viscosity (or small data).
