Minimum weight with stress constraints topology optimization
(2003)
[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 ...
A BEM formulation for computational design of grounding systems in stratified soils
(Centro Internacional de Métodos Numéricos en Ingeniería, 1998)
[Abstract] Substation grounding design involves computing the equivalent resistance of the earthing system -for reasons of equipment protection-, as well as distribution of
potentials on the earth surface -for reasons of ...
Numerical approaches for grounding installations in uniform and stratified soils
(2002)
[Abstract] This paper summarizes the main numerical approaches based on the BEM developed by the authors in the last years for the grounding analysis of electrical installations in uniform and layered soils.
High order shape design sensitivity: an unified approach
(Centro Internacional de Métodos Numéricos en Ingeniería, 1998)
[Abstract] Three basic analytical approaches have been proposed for the calculation
of sensitivity derivatives in shape optimization problems. The first approach is based
on differentiation of the discretized equations. ...
Modelización numérica de problemas de potenciales transferidos por redes de tierra mediante el método de los elementos de contorno
(2004)
[Resumen] El análisis y diseño de tomas de tierra en subestaciones eléctricas requiere el cálculo de la distribución de los niveles de potencial sobre la superficie del terreno y la resistencia equivalente de la red de ...
Sobre el empleo de técnicas de mínimos cuadrados móviles en el desarrollo de métodos de alta resolución de volúmenes finitos en mallas no estructuradas. Aplicación a problemas de flujo comprensible
(2005)
En este artículo se propone la combinación de aproximaciones por mínimos
cuadrados móviles y esquemas upwind de volúmenes finitos, aplicados a problemas de flujo
compresible en mallas no estructuradas. La construcción ...
Stabilization of numerical formulations for convective-diffussive transport problems
(The International Center of Numerical Methods in Engineering, 2000)
[Abstract] Numerical simulation in Fluid Mechanics is an extremely difficult task, wich complexity increases exponentially as the velocity of the fluid becomes higher. In particular, it is know that serious troubles are ...
