A Penalty Method for Approximations of the Stationary Power-Law Stokes Problem

Lefton, Lew; Wei, Dongming (Electronic journal of differential equations, 2001)

We study approximations of the steady state Stokes problem governed by the power-law model for viscous incompressible non-Newtonian flow using the penalty formulation. We establish convergence and find error estimates.
Penalty finite element approximations of the stationary power- law Stokes problem

Lefton, Lew; Wei, Dongming (Journal of Numerical Mathematics, 2003)

Finite element approximations of the stationary power-law Stokes problem using penalty formulation are considered. A priori error estimates under appropriate smoothness assumptions on the solutions are established without ...
