Hybrid H-matrix/FMM solvers for antennas and RCS problems

Autor: Denis Barbier, Toufic Abboud

Publikováno v: 2017 IEEE Conference on Antenna Measurements & Applications (CAMA).

We present Hi-BqX a generic library implementing state-of-the-art fast direct H-matrix, iterative Fast Multipole Method (FMM) solvers and their hybridization for existing codes based on Boundary Element Method (BEM) or Method of Moments (MoM). Parall

Coupling harmonic functions-finite elements for solving the stream function-vorticity Stokes problem

Autor: Toufic Abboud, Michel Salaün, Stéphanie Salmon

Publikováno v: Numerical Methods for Partial Differential Equations. 20:765-788

We consider the bidimensional Stokes problem for incompressible fluids in stream function-vorticity form. The classical finite element method of degree one usually used does not allow the vorticity on the boundary of the domain to be computed satis

Integral method for the Stokes problem

Autor: Stéphanie Salmon, Michel Salaün, Toufic Abboud

Publikováno v: Comptes Rendus Mathematique. 334:71-76

We consider the bidimensional Stokes problem for incompressible fluids in stream function-vorticity formulation. For this problem, the classical finite elements method of degree one converges only in O ( h ) for the quadratic norm of the vorticity, i

International audience; This work deals with the numerical simulation of wave propagation on unbounded domains with localized heterogeneities. To do so, we propose to combine a discretization based on a discontinuous Galerkin method in space and expl
