Comparison of SUPG with Bubble Stabilization Parameters and the Standard SUPG

open access: yesAbstract and Applied Analysis, 2014
We study a streamline upwind Petrov-Galerkin method (SUPG) with bubble stabilization coefficients on quasiuniform triangular meshes. The new algorithm is a consistent Petrov-Galerkin method and shows similar numerical performances as the standard SUPG ...

A hybrid perturbation-Galerkin method for differential equations containing a parameter [PDF]

open access: yes
A two-step hybrid perturbation-Galerkin method to solve a variety of differential equations which involve a parameter is presented and discussed. The method consists of: (1) the use of a perturbation method to determine the asymptotic expansion of the ...

Recent developments in stabilized Galerkin and collocation meshfree methods

open access: yesComputer Assisted Methods in Engineering and Science, 2017
Meshfree methods have been developed based on Galerkin type weak formulation and strong formulation with collocation. Galerkin type formulation in conjunction with the compactly supported approximation functions and polynomial reproducibility yields ...

-Error Estimates of the Extrapolated Crank-Nicolson Discontinuous Galerkin Approximations for Nonlinear Sobolev Equations

open access: yesJournal of Inequalities and Applications, 2010
We analyze discontinuous Galerkin methods with penalty terms, namely, symmetric interior penalty Galerkin methods, to solve nonlinear Sobolev equations.

Calculation of dispersion characteristics of regular waveguide with arbitrary dielectric filling with spectral method

open access: yesФизика волновых процессов и радиотехнические системы, 2013
By the means of spectral method the universal algorithm of calculation of dispersion characteristics of regular waveguide with arbitrary dielectric filling is presented. The method is based upon presenting of guiding structures fields as serial expansion
