Fuzzy stochastic elements method. Spectral approach

Mechanical Systems and Signal Processing, 2013
Abstract We study a complex dynamic problem, which concerns a structure with uncertain parameters subjected to a stochastic excitation. Formulation of such a problem introduces fuzzy random variables for parameters of the structure and fuzzy stochastic processes for the load process.

Nonconforming spectral/hp element methods for elliptic systems

Journal of Numerical Mathematics, 2009
The authors propose a nonconforming spectral\(/hp\) element method for solving elliptic systems on non-smooth domains using parallel computers. A geometric mesh is used in a neighbourhood of the corners and a modified set of polar coordinates is introduced in these neighbourhoods. Cartesian coordinates are used in the remaining part of the domain.

On A New Boundary Element Spectral Method

1987
An efficient numerical algorithm for partial differential equations in complicated 3-D geometries is developed in case of viscous fluid flows. The algorithm consists essentially of a combination of a boundary element method (where the resulting linear algebraic system is solved efficiently with a multigrid procedure) and a spectral method to treat the ...

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 ...
