These figures show the viscosity, the velocity streamlines, and the velocity vector directions arising from the numerical simulation, via an augmented mixed finite element method, of the Navier-Stokes equations with variable viscosity in the lid driven cavity. The main novelty is the utilization, as an auxiliary unknown, of a modified pseudostress tensor involving the diffusive and convective terms. Further details can be found in:
