On the anomalous asymptotic performance of the regular computer methods for grounding analysis
(2003)
[Abstract] Grounding systems are designed to guarantee personal security, protection of equipments
and continuity of power supply. Hence, engineers must compute the equivalent
resistance of the system and the potential ...
Una formulación alternativa para el problema del transporte por convección-difusión
(2004)
[Resumen] La resolución numérica de problemas de dinámica de fluidos es muy compleja. En concreto, la resolución numérica de la ecuación del transporte por convección–difusión es
tremendamente complicada a pesar de ser ...
A numerical approach based on the BEM for computing transferred earth potentials in grounding analysis
(2003)
[Abstract] In this paper we present a numerical approach based on the Boundary Element Method for the analysis
of a very common problem in electrical engineering practice: the existence of transferred earth potentials
in ...
Modelling Free-surface flows by a Galerkin based SPH formulation
(2003)
[Abastract] An algorithm based on Moving Least Squares Particle Hydrodynamics (MLSPH) to solve free surface flow is presented. MLS shape functions remarkably improve stability
and accuracy of standard SPH algorithms, ...
Un planteamiento generalizado para el problema de convención-difusión. Formulación numérica y aplicaciones
(2005)
Obtener una solución numérica precisa y estable de la ecuación de convección-difusi
ón requiere un gran coste computacional en situaciones de convección dominante.
Además, la formulación clásica del problema no es ...
A unified approach for high order sensitivity analysis
(Computational Mechanics Publications, 2001)
[Abstract] Many engineering problems require solving PDEs by means of numerical methods (type FEM/BEM) which sensivity analysis entails taking derivatives of functions defined through integration. In sizing optimization ...
A meshless numerical approach for the analysis of earthing systems in electrical installations
(Technische Universität München, 1999)
[Abstract] In the last three decades some numerical formulations have been developed for solving potential problems in electrical engineering applications. In the particular case of the grounding analysis area, in recent ...
Meshless methods applied to potential flow problems
(Elsevier, 2001)
[Abstract] In this paper we discuss some of the meshless approaches that have been recently proposed for solving boundary value problems. Several functional approximations and different integration schemes are studied. In ...
Petrov-Galerkin and Galerkin/Least Squares stabilized approaches for advectivediffusive transport problems
(Fundacja Zdrowia Publicznego "Vesalius", 2001)
[Abstract] The Finite Element method with a Galerkin type weighting is a straight-forward weighted residual method that has been sucessfuly used in many engineering applications, specially in Solid Mechanics. However, this ...
