Hybrid Laplace transform ®nite element method for solving the convection±dispersion problem
It can be very time consuming to use the conventional numerical methods, such as the ®nite element method, to solve convection± dispersion equations, especially for solutions of large-scale, long-term solute transport in porous media. In addition, the conventional methods are subject to arti®cial diusion and oscillation when used to solve convection-dominant solute transport problems. In this ...
متن کاملA Hybrid Mortar Finite Element Method for the Stokes Problem
In this paper, we consider the discretization of the Stokes problem on domain partitions with non-matching meshes. We propose a hybrid mortar method, which is motivated by a variational characterization of solutions of the corresponding interface problem. For the discretization of the subdomain problems, we utilize standard inf-sup stable finite element pairs. The introduction of additional unk...
متن کاملA Hybrid Finite Element-Laplace Transform Method for the Analysis of Transient Electromagnetic Scattering by anOver-FilledCavity in theGround Plane
A hybrid finite element-Laplace transform method is implemented to analyze the time domain electromagnetic scattering induced by a 2-D overfilled cavity embedded in the infinite ground plane. The algorithm divides the whole scattering domain into two, interior and exterior, sub-domains. In the interior sub-domain which covers the cavity, the problem is solved via the finite element method. The ...
متن کاملFinite element discretization of a thermoelastic beam
We consider the steady case of a nonlinear model for a thermoelastic beam that can enter in contact with obstacles. We first prove the well-posedness of this problem. Next, we propose a finite element discretization and perform the a priori and a posteriori analysis of the discrete problem. Some numerical experiments confirm the interest of this approach. Résumé: Nous considérons le cas station...
متن کاملSuperconvergence in the generalized finite element method
In this paper, we address the problem of the existence of superconvergence points of approximate solutions, obtained from the Generalized Finite Element Method (GFEM), of a Neumann elliptic boundary value problem. GFEM is a Galerkin method that uses non-polynomial shape functions, and was developed in [4, 5, 24]. In particular, we show that the superconvergence points for the gradient of the ap...
