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 ...
Galerkin, Least-Squares and GLS numerical approaches for advective-diffussive transport problems in engineering
(The International Center of Numerical Methods in Engineering, 2000)
[Abstract] In this paper, a study of three FE numerical formulations (Galerkin, Least Squares and Galerkin/Least Squares) applied to the convective-diffuse problem is presented, focusing our attention in high Péclet-number ...
Computing stabilization parameters in numerical models for advective-diffusive transport problems
(Universidade de Aveiro, 2000)
[Abstract] Numerical modelling in Fluid Mechanics is particulary difficult in high-advective fluid problems. The Finite Element Method, which has been sucessfully applied to very challenging problems in Computational ...
An enriched meshless numerical approach for potential theory problems
(The International Center of Numerical Methods in Engineering, 2000)
[Abstract] One of the meshless thechniques that have been recently proposed for solving Boundary Value Problems is the so-called Weighted Least Square (WLS) Method with a Point Collocation approach. Meshless methods were ...
Parallel computing aided design of earthing systems for electrical substations in non homogeneous soil models
(IEEE Computer Society, 2000)
[Abstract] An accurate design of grounding systems is essential to assure the safety of the persons, to protect the equipment and to avoid interruptions in the power supply. In order to attain these targets, the equivalent ...
A general numerical model for grounding analysis in layered soils
(Civil-Comp, 2000)
[Abstract] The safety of the persons, the protection of the equipment and the continuity of the power supply are the main objectives of the grounding system of a large electrical installation. For its accurate design, it ...
Enrichment of weighted least-squares approaches for potential problems in engineering applications
(Universidade de Aveiro, 2000)
[Abstract] In this paper, we review one of the meshless methods proposed in last years for solving boundary value problems based on a weighed least square methods. Furthermore, we analyze the use of enrichment techniques ...
Numerical modelling for grounding grids in high-performance parallel computers
(WIT, 2000)
[Abstract] The design of safe grounding systems in electrical installations is essential to assure the security of the persons, the protection of the equipment and the continuity of the power supply [1,2]. In order to ...
High Order Shape Design Sensitivity: A Unified Approach
(Elsevier, 2000)
[Abstract] Three basic analytical approaches have been proposed for the calculation of sen-
sitivity derivatives in shape optimization problems. The first approach is based on
differentiation of the discretized equations ...
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 ...
