Spectral/hp element methods: recent developments, applications, and perspectives [PDF]

open access: yes, 2018
The spectral/hp element method combines the geometric flexibility of the classical h-type finite element technique with the desirable numerical properties of spectral methods, employing high-degree piecewise polynomial basis functions on coarse finite ...

Large-eddy simulation of the lid-driven cubic cavity flow by the spectral element method [PDF]

open access: yes, 2007
This paper presents the large-eddy simulation of the lid-driven cubic cavity flow by the spectral element method (SEM) using the dynamic model. Two spectral filtering techniques suitable for these simulations have been implemented.

Spectral element method simulation of three-dimensional sedimentary basin under reverse-fault earthquakes

open access: yes地震科学进展, 2020
Near-fault ground motion can cause serious earthquake disaster in the near-field area,especially when there is sedimentary topography in the area. At present,there are no reports on the ground motion response of sedimentary basins under the action of ...

Generalized multiscale finite element methods for wave propagation in heterogeneous media [PDF]

open access: yes, 2013
Numerical modeling of wave propagation in heterogeneous media is important in many applications. Due to the complex nature, direct numerical simulations on the fine grid are prohibitively expensive.

Stable Spectral Methods on Tetrahedral Elements

open access: yesSIAM Journal on Scientific Computing, 2000
The authors present a framework for the construction of stable spectral methods on arbitrary domains with unstructured grids. They identify nodal sets suitable for polynomial interpolation on a tetrahedron and formulate stable spectral schemes on such unstructured nodal sets.

Mixed Mimetic Spectral Element method applied to Darcy's problem

open access: yes, 2013
We present a discretization for Darcy's problem using the recently developed Mimetic Spectral Element Method. The gist lies in the exact discrete representation of integral relations.
