A generalized statement for advective-diffusive phenomena. Finite element model and applications
(John Wiley and Sons, 2000)
[Abstract] Solving convective-diffusive transport problems is a frequent task in engineering, especially in
convection dominated situations. Moreover, the standard statement for the transport problem leads to
the result ...
Boundary element formulation for the analysis of transferred potentials in electrical installations
(Elsevier, 2004)
[Abstract] In this work we present a BEM numerical formulation for the analysis of a common problem in electrical engineering practice, that is, the existence of transferred earth potentials in a grounding installation ...

Analysis of transferred earth potentials in grounding systems: a BEM numerical approach
(IEEE Power Engineering Society, 2003)
[Abstract] In this work we present a numerical formulation for the analysis of a common problem in electrical engineering
practice, that is, the existence of transferred earth potentials
in a grounding installation [1]. ...
A minimum weight FEM formulation for Structural Topological Optimization with local stress constraints
(2005)
Since Bendsoe and Kikuchi proposed the basic concepts in 1988, most of topology structural optimization
results have been obtained so far by means of a maximum stiffness (minimum strain energy, minimum
compliance) approach. ...
Fluid flow simulation by Lagrangian particle methods
(2004)
[Abstract] In this paper we present a Galerkin based SPH formulation with moving least
squares meshless approximation, applied to free surface flows. The Galerkin scheme provides
a clear framework to analyze several ...
Optimización de torres de alta tensión mediante un método de programación lineal secuencial con búsqueda unidireccional cuadrática
(2005)
En este trabajo se presenta un sistema de optimización estructural desarrollado
específicamente para una determinada familia de problemas. El sistema permite
parametrizar automáticamente torres de alta tensión de tipos ...
Computer analysis of earthing systems in horizontally or vertically layered soils
(Elsevier, 2001)
[Abstract] The main objectives of grounding systems are to guarantee the personal safety, the equipment protection and the continuity of the power supply. To attain these goals, the potential distribution on the earth ...
Application of meshless methods to the analysis and design of grounding systems
(Centro Internacional de Métodos Numéricos en Ingeniería, 1998)
[Abstract] Analysis and design of grounding systems of electrical installations involves computing
the potential distribution in the earth and the equivalent resistance of the system.
Several numerical formulations based ...
A stabilized finite element approach for advective-diffusive transport problems
(Escola Politécnica da Universidade de Sao Paulo, 1999)
[Abstract] As it is well-know, the numerical simulation in fluid mechanics is quite difficult specially when the velocity of the fluid is important. These problems are reflected in the apparearance of numerical oscillations ...
