Transformation Methods for Static Field Problems With Random Domains [PDF]

open access: yes, 2011
The numerical solution of partial differential equations onto random domains can be done by using a mapping transforming this random domain into a deterministic domain. The issue is then to determine this one to one random mapping.

Time-decoupled high order continuous space-time finite element schemes for the heat equation [PDF]

open access: yes, 2014
Copyright © by SIAMIn Comput. Methods Appl. Mech. Engrg., 190 (2001), pp. 6685—6708 Werder et al. demonstrated that time discretizations of the heat equation by a temporally discontinuous Galerkin finite element method could be decoupled by diagonalising

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.

Multi-element stochastic reduced basis methods [PDF]

open access: yes, 2007
This paper presents mutli-element Stochastic Reduced Basis Methods (ME-SRBMs) for solving linear stochastic partial differential equations. In ME-SRBMs, the domain of definition of the random inputs is decomposed into smaller subdomains or random ...

Efficient method for the solution of Maxwell’s equations for nanostructured materials [PDF]

open access: yesITM Web of Conferences, 2019
The calculation of the electromagnetic field in nanostructured materials and nano-optoelectronic devices, when the wavelength of the incident radiation is comparable with the size of the structural elements, requires the exact solution of Maxwell's ...

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 ...
