Galerkin, Least-Squares and GLS numerical approaches for advective-diffussive transport problems in engineering
(The International Center of Numerical Methods in Engineering, 2000)
[Abstract] In this paper, a study of three FE numerical formulations (Galerkin, Least Squares and Galerkin/Least Squares) applied to the convective-diffuse problem is presented, focusing our attention in high Péclet-number ...
Computing stabilization parameters in numerical models for advective-diffusive transport problems
(Universidade de Aveiro, 2000)
[Abstract] Numerical modelling in Fluid Mechanics is particulary difficult in high-advective fluid problems. The Finite Element Method, which has been sucessfully applied to very challenging problems in Computational ...
An enriched meshless numerical approach for potential theory problems
(The International Center of Numerical Methods in Engineering, 2000)
[Abstract] One of the meshless thechniques that have been recently proposed for solving Boundary Value Problems is the so-called Weighted Least Square (WLS) Method with a Point Collocation approach. Meshless methods were ...
Development of integration schemes for meshless numerical approaches based on the SPH method
(The Institute of Mathematics and its Applications, 2001)
[Abstract] In this paper we discuss some of the meshless formulations that have been recently proposed for solving Boundary Value Problems. Several functional approximations are studied both, from a continuum and from a ...
Parallel computing aided design of earthing systems for electrical substations in non homogeneous soil models
(IEEE Computer Society, 2000)
[Abstract] An accurate design of grounding systems is essential to assure the safety of the persons, to protect the equipment and to avoid interruptions in the power supply. In order to attain these targets, the equivalent ...

A minimum weight with stress constraints FEM approach for topology structural optimization problems
(2002)
[Abstract] Sizing and shape structural optimization problems are normally stated in terms of a minimum weight
approach with constraints that limit the maximum allowable stresses and displacements.
However, topology ...
