Parallelization of Spectral Element Methods
2003Spectral element methods allow for effective implementation of numerical techniques for partial differential equations on parallel architectures. We present two implementations of the parallel algorithm where the communications are performed using MPI. In the first implementation, each processor deals with one element.

Constraint Oriented Spectral Element Method
2010An original polynomial approximation to solve partial differential equations is presented. This spectral element version takes into account the underlying nature of the corresponding physical problem. For different types of operators, this approach allows to all terms in a variational form to be represented by the same functional dependence and by the ...

The spectral-element method is a high-order numerical method that allows us to solve the seismic wave equation in 3D heterogeneous Earth models. The method enables adaptation of the mesh to the irregular surface topography and to the variable wavelengths inside the Earth. Moreover, the spectral-element method yields accurate solutions for surface waves

Chapter 8 introduces multidomain methods to compute problems in geometries that are more complex than a quadrilateral with curved sides. In multidomain spectral methods, and spectral element methods in particular, the domain of interest is subdivided into smaller subdomains that are mapped individually onto the square, allowing problems in truly ...

Mixed Spectral-Element Method for the Waveguide Problem With Bloch Periodic Boundary Conditions
IEEE transactions on electromagnetic compatibility (Print), 2018The mixed spectral-element method (MSEM) is applied to solve the waveguide problem with the Bloch periodic boundary condition (BPBC). Based on the BPBC for the original Helmholtz equation and the periodic boundary condition (PBC) for the equivalent but ...
