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 ...
A boundary element numerical approach for earthing grid computation
(Elsevier, 1999)
[Abstract] Analysis and design of substation earthing involves computing the equivalent resistance of grounding systems, as well as distribution of potentials on the earth
surface due to fault currents [1,2]. While very ...

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 ...
