We study equations to describe incompressible generalized Newtonian fluids, where the extra stress tensor satisfies a nonstandard anisotropic asymptotic growth condition. An implicit finite element discretization and a simple, fully practical fixed-point scheme with proper thresholding criterion are proposed, and convergence toward weak solutions of the limiting problem is shown. Computational experiments are included, which motivate nontrivial fluid flow behavior.
