A 2D numerical model for the transport of pollutants. The influence of Boundary Conditions
(Utah State University Extension, 1999)[Abstract] The pollutants transport phenomena in a 2D unsteady free surface flow has been studied. The weighted residual method has been used for the integration of the transport equations, appying the Galerkin formulation ... -
A fully discrete BEM-FEM method for an exterior elasticity system in the plane
(Elsevier BV * North-Holland, 2001)[Abstract] We present a modified version of the usual BEM–FEM coupling for the exterior elasticity problem in the plane (cf. Costabel and Stephan, SIAM J. Numer. Anal. 27 (1990) 1212–1226). This new formulation allows us ... -
A minimum weight FEM formulation for Structural Topological Optimization with local stress constraints
(2005)Since Bendsoe and Kikuchi proposed the basic concepts in 1988, most of topology structural optimization results have been obtained so far by means of a maximum stiffness (minimum strain energy, minimum compliance) approach. ... -
Definition of an Artificial Reef Unit through Hydrodynamic and Structural (CFD and FEM) Models—Application to the Ares-Betanzos Estuary
(MDPI, 2022)[Abstract] The application of hydrodynamics to the definition of artificial reefs is of great interest since the positioning of the artificial reef modules on the sea floor alters the water velocity field, causing an ... -
Exploiting locality in the run-time parallelization of irregular loops
(C R C Press, LLC, 2002-12-10)[Abstract] The goal of this work is the efficient parallel execution of loops with indirect array accesses, in order to be embedded in a parallelizing compiler framework. In this kind of loop pattern, dependences can not ... -
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 ... -
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. ... -
Pure Lagrangian and Semi-Lagrangian Finite Element Methods for the Numerical Solution of Convection-Diffusion Problems
(University of Alberta, Northwestern Polytechnical University, Institute for Scientific Computing, 2014)[Abstract]: In this paper we propose a unified formulation to introduce and analyze (pure) Lagrangian and semi-Lagrangian methods for solving convection-diffusion partial differential equations. This formulation allows us ... -
Topology optimization of structures considering minimum weight and stress constraints by using the Overweight Approach
(Elsevier, 2022)[Abstract:] In this paper, a new method for structural topology optimization considering minimum weight and local stress constraints is proposed. For this purpose, the Overweight Approach, an improvement of the so-called ...
