چکیده

We present a simple filtering procedure for stabilizing the spectral element method (SEM) for the unsteady advection-diffusion and Navier-Stokes equations. A number of example applications are presented, along with basic analysis for the advection-diffusion case. Stabilisation par filtrage pour la méthode des éléments spectraux Résumé. Nous présentons une procédure simple de filtrage pour la stabilisation de la méthode des éléments spectraux (SEM) appliquée à des équations de convection-diffusion et de Navier-Stokes. Cette procédure est mise en oeuvre sur un grand nombre d’exemples, et une analyse élémentaire est réalisée sur un cas de convection-diffusion.

Variational multiscale stabilization of high-order spectral elements for the advection-diffusion equation

One major issue in the accurate solution of convection-dominated problems by means of high-order methods is the ability of the solver to maintain monotonicity. This problem is critical for spectral elements, where Gibbs oscillations may pollute the solution. However, typical filter-based stabilization techniques used with spectral elements are not monotone. In this paper, residual-based stabili...

Vibration and Stability of Axially Moving Plates by Standard and Spectral Finite Element Methods

Based on classical plate theory, standard and spectral finite element methods are extended for vibration and dynamic stability of axially moving thin plates subjected to in-plane forces. The formulation of the standard method earned through Hamilton’s principle is independent of element type. But for solving numerical examples, an isoparametric quadrilateral element is developed using Lagrange ...

On the natural stabilization of convection diffusion problems using LPIM meshless method

By using the finite element $p$-Version in convection-diffusion problems, we can attain to a stabilized and accurate results. Furthermore, the fundamental of the finite element $p$-Version is augmentation degrees of freedom. Based on the fact that the finite element and the meshless methods have similar concept, it is obvious that many ideas in the finite element can be easily used in the meshl...

Stabilization Methods for Spectral Element Computations of Incompressible Flows

A stabilization method for the spectral element computation of incompressible flow problems is investigated. It is based on a filtering procedure which consists in filtering the velocity field by a spectral vanishing Helmholtz-type operator at each time step. Relationship between this filtering procedure and SVV-stabilization method, introduced recently in [JCP, 2004, 196(2), p680], is establis...
