We provide some extensions to the AMGe method (algebraic multigrid method based on element interpolation), concerning the agglomeration process, the application to non-conforming elements, and the application to the mixed finite element discretization of the Oseen-linearized Navier-Stokes equations. This last point, using AMGe for mixed finite elements, gets straight-forward because of the avai...

In this work, we are concerned with the finite element approximation for the stationary power law Stokes equations driven by nonlinear slip boundary conditions of ‘friction type’. After the formulation of the problem as mixed variational inequality of second kind, it is shown by application of a variant of Babuska– Brezzi’s theory for mixed problems that convergence of the finite element approx...
