WebThe Raviart-Thomas Mixed Finite Element method of lowest order satisfies these properties. Moreover both the pressure and the velocity are approximated with the same order of convergence (see, e.g., [11, 13]). One of the inconvenient properties of this method is that it leads to an indefinite linear system, ...
