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 ...

Finite Elements and Spectral Methods

2014
In this chapter, the weighted residual methods are introduced. These methods represent the solution as a series of basis functions whose coefficients are determined to make the PDE (and BC) residuals as small as possible (in an average sense). In particular, attention is focused on the Galerkin and collocation methods, and the use of global and local ...

Finite-Element Preconditioning of G-NI Spectral Methods

SIAM Journal on Scientific Computing, 2010
Several old and new finite-element preconditioners for nodal-based spectral discretizations of $-\Delta u=f$ in the domain $\Omega=(-1,1)^d$ ($d=2$ or 3), with Dirichlet or Neumann boundary conditions, are considered and compared in terms of both condition number and computational efficiency. The computational domain covers the case of classical single-

Mimetic spectral element methods

AIP Conference Proceedings, 2015
Mimetic spectral element methods are arbitrary order methods which aim to mimic the underlying physical structure of a PDE. This is best accomplished in terms of differential geometry in which the physical variables are considered as differential k-forms. At the discrete level, the system is represented by k-cochains from algebraic topology.

Spectral Finite Element Method

2016
Spectral finite element method (SFEM) is an efficient technique for solving problems where the frequency content of the input signal is very high. The spectral formulation requires that the assembled system of equations be solved in the frequency domain and utilizes the Fast Fourier Transform (FFT) to transform the time domain responses to the ...
