Inf-sup Stable Nonconforming Finite Elements of Higher Order on Quadrilaterals and Hexahedra
Abstract. We present families of scalar nonconforming finite elements of arbitrary order r ≥ 1 with optimal approximation properties on quadrilaterals and hexahedra. Their vector-valued versions together with a discontinuous pressure approximation of order r − 1 form inf-sup stable finite element pairs of order r for the Stokes problem. The well-known elements by Rannacher and Turek are recover...
متن کاملPseudo-conforming Polynomial Lagrange Finite Elements on Quadrilaterals and Hexahedra
The aim of this paper is to develop a new class of finite elements on quadrilaterals and hexahedra. The degrees of freedom are the values at the vertices and the approximation is polynomial on each element K. In general, with this kind of finite elements, the resolution of second order elliptic problems leads to non-conforming approximations.Degrees of freedom are the same than those of isopara...
متن کاملPseudo-conforming Hdiv polynomial finite elements on quadrilaterals and hexahedra
The aim of this paper is to present a new class of mixed finite elements on quadrilaterals and hexahedra where the approximation is polynomial on each element K. The degrees of freedom are the same as those of classical mixed finite elements. However, in general, with this kind of finite elements, the resolution of second order elliptic problems leads to non conforming approximations. In the pa...
متن کاملP1-Nonconforming Finite Elements on Triangulations into Triangles and Quadrilaterals
The P1-nonconforming finite element is introduced for arbitrary triangulations into quadrilaterals and triangles of multiple connected Lipschitz domains. An explicit a priori analysis for the combination of the Park–Sheen and the Crouzeix–Raviart nonconforming finite element methods is given for second-order elliptic PDEs with inhomogeneous Dirichlet boundary conditions.
متن کاملNew robust nonconforming finite elements of higher order
We study second order nonconforming finite elements as members of a new family of higher order approaches which behave optimally not only on multilevel refined grids, but also on perturbed grids which are still shape regular but which consist no longer of asymptotically affine equivalent mesh cells. We present two approaches to prevent this order reduction: The first one is based on the use of ...
