Journal ArticleDOI
Upwind methods for hyperbolic conservation laws with source terms
TL;DR: Methods to get natural upwind discretizations of the source term when the flux is approximated by using flux-difference or flux-splitting techniques are given.
Journal ArticleDOI
Upwind schemes for the two-dimensional shallow water equations with variable depth using unstructured meshes
TL;DR: In this paper, the authors extended well-known upwind schemes for hyperbolic equations to solve the two-dimensional Saint-Venant (or shallow water) equations and compared the resulting schemes in terms of a conservation property.
Journal ArticleDOI
An optimal perfectly matched layer with unbounded absorbing function for time-harmonic acoustic scattering problems
TL;DR: An optimal bounded perfectly matched layer (PML) technique is introduced by choosing a particular absorbing function with unbounded integral that is easy to implement in a finite element method and overcomes the dependency of parameters for the discrete problem.
Journal ArticleDOI
Duality methods for solving variational inequalities
Alfredo Bermúdez,C. Moreno +1 more
TL;DR: Methods of maximal monotone operators are used in order to study duality numerical algorithms for solving variational inequalities and some new algorithms appear to have very good numerical performances.
Journal ArticleDOI
Finite element computation of the vibration modes of a fluid—solid system
TL;DR: In this paper, the interior elastoacoustic problem is solved by a finite element method, which does not present spurious or circulation modes for nonzero frequencies, and consists of classical triangular lagrangian elements for the solid and lowest order triangular Raviart-Thomas elements for fluid.
