We considerH(curl; Î©)-elliptic problems that have been discretized by means of NÃ©dÃ©lecâ€™s edge elements on tetrahedral meshes. Such problems occur in the numerical computation of eddy currents. Fromâ€¦ (More)

An adaptive mixed finite element method (AMFEM) is designed to guarantee an error reduction, also known as saturation property: after each refinement step, the error for the fine mesh is strictlyâ€¦ (More)

An adaptive nonconforming finite element method is developed and analyzed that provides an error reduction due to the refinement process and thus guarantees convergence of the nonconforming finiteâ€¦ (More)

In this paper, we develop and analyze a new model describing electrorheological fluid flow. In contrast to existing models, which assume the electric field to be perpendicular to the velocity fieldâ€¦ (More)

We consider mixed finite element discretizations of linear second order elliptic boundary value problems with respect to an adaptively generated hierarchy of possibly highly nonuniform simplicialâ€¦ (More)

We introduce a technique for the dimension reduction of a class of PDE constrained optimization problems governed by linear time dependent advection diffusion equations for which the optimizationâ€¦ (More)

The adaptive algorithm for the obstacle problem presented in this paper relies on the jump residual contributions of a standard explicit residual-based a posteriori error estimator. Each cycle of theâ€¦ (More)

In this paper we consider second order scalar elliptic boundary value problems posed over threeâ€“dimensional domains and their discretization by means of mixed Raviartâ€“Thomas finite elements [18].â€¦ (More)
