Adaptive variational multiscale methods for incompressible flow based on two local Gauss integrations
نویسندگان
چکیده
We consider variational multiscale (VMS) methods with h-adaptive technique for the stationary incompressible Navier–Stokes equations. The natural combination of VMS with adaptive strategy retains the best features of both methods and overcomes many of their deficits. A reliable a posteriori projection error estimator is derived, which can be computed by two local Gauss integrations at the element level. Finally, some numerical tests are presented to illustrate the method’s efficiency. 2010 Elsevier Inc. All rights reserved.

A finite element variational multiscale method for incompressible flow
In this article, we present a finite element variational multiscale (VMS) method for incompressible flows based on two local Gauss integrations, and compare it with common VMS method which is defined by a low order finite element space Lh on the same grid as Xh for the velocity deformation tensor and a stabilization parameter a. The best algorithmic feature of our method is using two local Gaus...
متن کاملA Finite Element Variational Multiscale Method Based on Two Local Gauss Integrations for Stationary Conduction-Convection Problems
A new finite element variational multiscale VMS method based on two local Gauss integrations is proposed and analyzed for the stationary conduction-convection problems. The valuable feature of our method is that the action of stabilization operators can be performed locally at the element level with minimal additional cost. The theory analysis shows that our method is stable and has a good prec...
متن کاملA variational multiscale method based on bubble functions for convection-dominated convection-diffusion equation
This work presents a variational multiscale method based on polynomial bubble functions as subgrid scale and a numerical implementation based on two local Gauss integrations. This method can be implemented easily and efficiently for the convection-dominated problem. Static condensation of the bubbles suggests the stability of the method and we establish its global convergence. Representative nu...
متن کاملA Parallel Variational Multiscale Method for Incompressible Flows Based on the Partition of Unity
A parallel variational multiscale method based on the partition of unity is proposed for incompressible flows in this paper. Based on two-grid method, this algorithm localizes the global residual problem of variational multiscale method into a series of local linearized residual problems. To decrease the undesirable effect of the artificial homogeneous Dirichlet boundary condition of local sub-...
متن کاملVariational Multiscale Methods for incompressible flows
The numerical simulation of incompressible flow governed by the Navier-Stokes equations requires to deal with subgrid phenomena. Particularly in turbulent flows, the scale spectra are notably widened and need to be handled adequately to get a reasonable numerical solution. Separating the complete scale range into subranges enables a different treatment of any of these subranges. In the brevity ...
