A two-dimensional adaptive spectral element method

13th Computational Fluid Dynamics Conference, 1997
An adaptive spectral element method is developed for the accurate capture of complex flow phenomena in direct numerical simulation of incompressible flows. The method relies on an a posteriori error estimators to determine regions of the domain requiring refinement. In this paper, only /i-refinement is used.

Spectral‐element method for high‐speed rotating cylinders

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2009
PurposeThe purpose of this paper is to offer a fast and reliable discretisation scheme for computing the electromagnetic fields inside a ferromagnetic cylinder, accounting for motional eddy currents under high velocities and accounting for the severe ferromagnetic saturation of the rotor surface.Design/methodology/approachA nonlinear spectral‐element ...

Edge Functions for Spectral Element Methods

2010
It is common practice in finite element methods to expand the unknowns in nodal functions. The discretization of the gradient, curl and divergence operators requires H 1, H(curl) and H(div) function spaces and their discrete representation. Especially in mixed formulations this involved quite some mathematical machinery which can be avoided once we ...

Spectral, Spectral Element and Mortar Element Methods

2001
The spectral and spectral element discretizations of partial differential equations rely on high degree polynomial approximation and on the use of tensorized bases of polynomials. Firstly, on a square or a cube, we describe the basic tools for spectral methods, and we prove some optimal properties of polynomial approximation and interpolation. We apply

Spectral Element Method for Cable Harnessed Structure

This paper presents a predictive model of a cable-harnessed structure through using the Spectral Element Method (SEM) and this is compared to a finite element approach. SEM is an element-based method that combines the generality of the finite element method with the accuracy of spectral techniques.
