The mixed finite element preconditioned conjugate gradient-Uzawa method for Stokes equations (English)
0 references
The authors consider solving the Stokes problem by a mixed finite element method based on a Taylor-Hood pair. In order to solve the linear algebraic counterpart, they use a preconditioned conjugate gradient Uzawa algorithm. Unfortunately, neither the theoretical arguments nor the numerical results carried out are able to clarify the convergence of the algorithm.
