The LBB condition for the Taylor - Hood P 2 − P 1 and Scott - Vogelius P 2 − discP 1 element pairs in 2 - D
نویسنده
چکیده
In this article we apply the Stenberg criteria to show that the Taylor-Hood P2 − P1 and the Scott-Vogelius P2 − discP1 element pairs satisfy the LBB condition in IR. The Taylor-Hood P2 − P1 pair is shown to be stable on a regular triangulation of the domain. For the ScottVogelius P2−discP1 element pair the mesh is assumed to be a barycenter refinement of a regular triangulation.

Stenberg’s sufficiency criteria for the LBB condition for Axisymmetric Stokes Flow
In this article we investigate the LBB condition for axisymmetric flow problems. Specifically, the sufficiency condition for approximating pairs to satisfy the LBB condition established by Stenberg in the Cartesian coordinate setting is presented for the cylindrical coordinate setting. For the cylindrical coordinate setting, the Taylor-Hood (k = 2) and conforming Crouzeix-Raviart elements are s...

متن کاملA Connection Between Scott-Vogelius and Grad-Div Stabilized Taylor-Hood FE Approximations of the Navier-Stokes Equations
This article studies two methods for obtaining excellent mass conservation in finite element computations of the Navier-Stokes equations using continuous velocity fields. With a particular mesh construction, the Scott-Vogelius element pair has recently been shown to be inf-sup stable and have optimal approximation properties, while also providing pointwise mass conservation. We present herein t...
متن کاملNew connections between finite element formulations of the Navier-Stokes equations
We show the velocity solutions to the convective, skew-symmetric, and rotational Galerkin finite element formulations of the Navier-Stokes equations are identical if Scott-Vogelius elements are used, and thus all three formulations will the same pointwise divergence free solution velocity. A connection is then established between the formulations for grad-div stabilized Taylor-Hood elements: un...

by elements of Taylor-Hood type. More specifically, for k = 2, 3, the velocity vector u is approximated in the space V k0,h = V k h ∩ H10(Ω), where V kh is the space of continuous piecewise polynomial vectors of degree ≤ k and the pressure p is approximated in the space Qk−1 h consisting of continuous piecewise polynomials of degree ≤ k−1. The stability of these pairs depends on verification of...
