On an adaptive stabilized mixed finite element method for the Oseen problem with mixed boundary conditions
We consider the Oseen problem with nonhomogeneous Dirichlet boundary conditions on a part of the boundary and a Neumann type boundary condition on the remaining part. Suitable least squares terms that arise from the ...
New a posteriori error estimator for an stabilized mixed method applied to incompressible fluid flows
(Applied Mathematics and Computation, 2019-06-15)
We consider an augmented mixed finite element method for incompressible fluid flows and develop a simple a posteriori error analysis. We obtain an a posteriori error estimator that is reliable and locally efficient. We ...
