Three-point finite-difference schemes, Padé and the spectral Galerkin method. I. One-sided impedance approximation
A method for calculating special grid placement for three-point schemes which yields exponential superconvergence of the Neumann to Dirichlet map has been suggested earlier. Here we show that such a grid placement can yield impedance which is equivalent to that of a spectral Galerkin method, or more generally to that of a spectral Galerkin-Petrov method. In fact we show that for every stable Ga...
متن کاملA discontinuous Galerkin Method for parabolic problems with modified hp-finite element approximation technique
A recent paper [Hideaki Kaneko, Kim S. Bey, Gene J.W. Hou, Discontinuous Galerkin finite element method for parabolic problems, preprint November 2000, NASA] is generalized to a case where the spatial region is taken in R. The region is assumed to be a thin body, such as a panel on the wing or fuselage of an aerospace vehicle. The traditional has well as hp-finite element methods are applied to...
متن کاملAn Approximation of the Error in Element Free Galerkin Method
The diffuse element method developed by Nayroles et al. is a new way for solving partial differential equations. In this method, only a mesh of nodes and a boundary description is needed to develop the Galerkin equations. The approximating functions are polynomials fitted to the nodal values of each local domain by a weighted least squares approximation. Belytschko et al. developed an alternati...
متن کامل- linearization BASED UPON DIFFERENTIAL APPROXIMATION AND GALERKIN ' S METHOD
We present a new linearization technique based upon differential approximation which is considerably simpler and more flexible than those used in our previous work.
متن کاملGalerkin Finite Element Method and Finite Difference Method for Solving Convective Non-linear Equation
The fast progress has been observed in the development of numerical and analytical techniques for solving convection-diffusion and fluid mechanics problems. Here, a numerical approach, based in Galerkin Finite Element Method with Finite Difference Method is presented for the solution of a class of non-linear transient convection-diffusion problems. Using the analytical solutions and the L2 and ...
