Numerische Simulation Auf Massiv Parallelen Rechnern Interpolation of Non-smooth Functions on Anisotropic Nite Element Meshes

چکیده
In this paper, several modiications of the quasi-interpolation operator of Scott and Zhang (Math. Comp. 54(1990)190, 483{493) are discussed. The modiied operators are deened for non-smooth functions and are suited for the application on anisotropic meshes. The anisotropy of the elements is reeected in the local stability and approximation error estimates. As an application, an example is considered where anisotropic nite element meshes are appropriate, namely the Poisson problem in domains with edges.

Numerische Simulation Auf Massiv Parallelen Rechnern Crouzeix-raviart Type Nite Elements on Anisotropic Meshes
The paper deals with a non-conforming nite element method on a class of anisotropic meshes. The Crouzeix-Raviart element is used on triangles and tetrahedra. For rectangles and prismatic (pentahedral) elements a novel set of trial functions is proposed. Anisotropic local interpolation error estimates are derived for all these types of element and for functions from classical and weighted Sobole...

The nite element method with anisotropic mesh grading for elliptic problems in domains with corners and edges Abstract. This paper is concerned with a speciic nite 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 nite element method with anisotropic, graded meshes and...
متن کاملNumerische Simulation Auf Massiv Parallelen Rechnern a Non-conforming Nite Element Method with Anisotropic Mesh Grading for the Stokes Problem in Domains with Edges
The solution of the Stokes problem in three-dimensional domains with edges has anisotropic singular behaviour which is treated numerically by using anisotropic nite element meshes. The velocity is approximated by Crouzeix-Raviart (non-conforming P 1) elements and the pressure by piecewise constants. This method is stable for general meshes (without minimal or maximal angle condition). The inter...
متن کاملNumerische Simulation Auf Massiv Parallelen Rechnern Error Estimation for Anisotropic Tetrahedral and Triangular Nite Element Meshes
Some boundary value problems yield anisotropic solutions, e.g. solutions with boundary layers. If such problems are to be solved with the nite element method (FEM), anisotropically reened meshes can be advantageous. In order to construct these meshes or to control the error one aims at reliable error estimators. For isotropic meshes many estimators are known, but they either fail when used on a...

In an anisotropic adaptive nite element algorithm one usually needs an error estimator that yields the error size but also the stretching directions and stretching ratios of the elements of a (quasi) optimal anisotropic mesh. However the last two ingredients can not be extracted from any of the known anisotropic a posteriori error estimators. Therefore a heuristic approach is pursued here, name...
