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 ...
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 ...
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 ...
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 ...
Stability analysis of BEM approximate solutions in grounding analysis
(Elsevier, 2001)
[Abstract] In this paper we present a summary of the Boundary Element Method developed for the analysis of potential problems
in the electrical engineering field. The numerical model proposed is shown as a general frame ...
A massively parallel BEM numerical model for grounding analysis in layered soils
(Fundacja Zdrowia Publicznego "Vesalius", 2001)
[Abstract] In the last years the authors have developed a numerical formulation based on the Boundary Element Method for the analysis of grounding systems embedded in uniform soils. This approach has been implemented in a ...
An efficient MP algorithm for structural shape optimization problems
(Computational Mechanics Publications, 2001)
[Abstract] Integral methods -such as the Finite Element Method (FEM) and the Boundary Element Method (BEM)- are frequently used in structural optimization problems to solve systems of partial differential equations. ...
