The Finite Element Method With Lagrange Multipliers for Domains With Corners
We study the convergence of the finite element method with Lagrange multipliers for approximately solving the Dirichlet problem for a second-order elliptic equation in a plane domain with piecewise smooth boundary. Assuming mesh refinements around the corners, we construct families of boundary subspaces that are compatible with triangular Lagrange elements in the interior, and we carry out the ...

An error analysis is presented for the approximation of the statiornary Stokes equations by a finite element method using Lagrange multipliers.
متن کاملThe Finite Element Immersed Boundary Method with Distributed Lagrange Multiplier
In this talk we consider the finite element discretization of the Immersed Boundary Method (IBM) introduced by Peskin [6] for fluid-structure interaction problems. With respect to the original finite differences discretization the finite element approach can take advantage from the variational formulation in handling the Dirac delta function which takes into account the presence of the structur...
متن کاملThe Finite Element Method with Anisotropic Mesh Grading for Elliptic Problems in Domains with Corners and Edges
This paper is concerned with a specific finite element strategy for solving elliptic boundary value problems in domains with corners and edges. First, the anisotropic singular behaviour of the solution is described. Then the finite element method with anisotropic, graded meshes and piecewise linear shape functions is investigated for such problems; the schemes exhibit optimal convergence rates ...
متن کاملHierarchical a Posteriori Error Estimators for Mortar Finite Element Methods with Lagrange Multipliers
Hierarchical a posteriori error estimators are introduced and analyzed for mortar nite element methods. A weak continuity condition at the interfaces is enforced by means of Lagrange multipliers. The two proposed error estimators are based on a defect correction in higher order nite element spaces and an adequate hierarchical two-level splitting. The rst provides upper and lower bounds for the ...
