چکیده

<p style='text-indent:20px;'>A stabilizer free WG method is introduced for the Stokes equations with superconvergence on polytopal mesh in primary velocity-pressure formulation. Convergence rates two order higher than optimal-order velocity of approximation proved both an energy norm and <inline-formula><tex-math id="M1">$ L^2 $</tex-math></inline-formula> norm. Optimal error estimate pressure id="M2">$ also established. The numerical examples cover low high approximations, 2D 3D cases.</p>

Adjoint-based Mesh Adaptation for the 3D Navier-Stokes Equations with the High-order CPR Method

The objective of the present work is to extend the adjoint-based error estimate and the adaptive mesh refinement algorithm of the high-order CPR method to the 3D NavierStokes equations. A dual-consistent high-order correction procedure via reconstruction method is utilized to obtain the adjoint solution and derive the output-based local error indicator. Several inviscid and viscous flow cases a...

Static and Free Vibration Analyses of Orthotropic FGM Plates Resting on Two-Parameter Elastic Foundation by a Mesh-Free Method

In this paper, static and free vibrations behaviors of the orthotropic functionally graded material (FGM) plates resting on the two-parameter elastic foundation are analyzed by the a mesh-free method based on the first order shear deformation plate theory (FSDT). The mesh-free method is based on moving least squares (MLS) shape functions and essential boundary conditions are imposed by transfer...

Global Superconvergence for Optimal Control Problems Governed by Stokes Equations

In this paper, the global superconvergence analysis for the finite element approximation of the distributed optimal control governed by Stokes equations is discussed. For the control, a global superconvergence result is derived by applying patch recovery technique. For the state and the co-state, the global superconvergence results are derived by applying some postprocessing techniques for the ...

A Mixed Finite Element Method on a Staggered Mesh for Navier-stokes Equations

In this paper, we introduce a mixed finite element method on a staggered mesh for the numerical solution of the steady state Navier-Stokes equations in which the two components of the velocity and the pressure are defined on three different meshes. This method is a conforming quadrilateral Q1 × Q1 − P0 element approximation for the Navier-Stokes equations. First-order error estimates are obtain...

A Two-level Defect–correction Method for Navier–stokes Equations

A two-level defect–correction method for the steady-state Navier–Stokes equations with a high Reynolds number is considered in this paper. The defect step is accomplished in a coarse-level subspace Hm by solving the standard Galerkin equation with an artificial viscosity parameter σ as a stability factor, and the correction step is performed in a fine-level subspace HM by solving a linear equat...
