Abstract

In this paper we have developed the numerical solution of two problems of diffusion-convection (DC), using the finite element method of Streamline Upwind Petrov-Galerkin (SUPG). The parameters that define the behavior of the equations are modeled as stochastic fields, specifically, [...]

Abstract

We present the design of a high-resolution Petrov–Galerkin (HRPG) method using linear finite elements
for the problem defined by the residual

R (phi):= partial phi /partial t + u partial [...]

A multidimensional extension of the HRPG method using the lowest order block finite elements [...]

Abstract

A Petrov–Galerkin formulation based on two different perturbations to the weighting functions is presented. These perturbations stabilize the oscillations that are normally exhibited [...]
