A 2D numerical model using finite volume method for sediment transport in rivers
(2002)
[Abstract] The study of rivers as ecosystems has many fields of research, like the resolution and comprehension
of flow and sediment transport phenomena. In this communication a 2D numerical model using the
Finite Volume ...
Numerical computation of grounding grids
(Asociación Argentina de Mecánica Computacional, 1995)
[Abstract] Grounding systems are designed to preserve human safety and grant the integrity
of equipments under fault conditions. To achieve these goals, the equivalent electrical
resistance of the system must be low ...
A general formulation based on the boundary element method for the analysis of grounded instalations in layered soils
(Computational Mechanics Publications, 1998)
[Abstract] The design of safe grounding systems requires computing the potential
level distribution on the earth surface for reasons of human security, as
well as the equivalent resistance of the earthing installation ...
Una formulación general de elementos de contorno para el diseño asistido por ordenador de tomas de tierra en subestaciones eléctricas
(Centro Internacional de Métodos Numéricos en Ingeniería, CIMNE (Barcelona), 1996)
[Resumen] La puesta a tierra de una instalación eléctrica es imprescindible para

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 ...
