  • Unified formulation of a family of iterative solvers for power systems analysis 

    Borzacchiello, Domenico; Chinesta, Francisco; Malik, Muhammad H.; García Blanco, Raquel; Díez, Pedro (2016-11)
    Article
    Accés restringit per política de l'editorial
    This paper illustrates the construction of a new class of iterative solvers for power flow calculations based on the method of Alternating Search Directions. This method is fit to the particular algebraic structure of the ...
  • Sticking and sliding of lipid bilayers on deformable substrates 

    Stubbington, L; Arroyo Balaguer, Marino; Staykova, M (2017-01)
    Article
    Accés obert
    We examine here the properties of lipid bilayers coupled to deformable substrates. We show that by changing the extent of the substrate hydrophilicity, we can control the membrane–substrate coupling and the response of the ...
  • Non-regularised inverse finite element analysis for 3D traction force microscopy 

    Muñoz Romero, José (2016-06-10)
    Article
    Accés obert
    The tractions that cells exert on a gel substrate from the observed displacements is an increasingly attractive and valuable information in biomedical experiments. The computation of these tractions requires in general ...
  • Charting molecular free-energy landscapes with an atlas of collective variables 

    Hashemian, B.; Millán, Raúl Daniel; Arroyo Balaguer, Marino (2016-11-07)
    Article
    Accés obert
    Collective variables (CVs) are a fundamental tool to understand molecular flexibility, to compute free energy landscapes, and to enhance sampling in molecular dynamics simulations. However, identifying suitable CVs is ...
  • Un estimador de error residual semiexplícito en cantidades de interés para un problema mecánico lineal 

    Rosales, R.; Díez, Pedro (2016-10)
    Article
    Accés obert
    We aim at defining a semi-explicit approach to estimate the error in quantities of interest associated with the Finite Element solution of a linear elasticity problem. The advocated procedure is split in two parts, an ...
  • Vademecum-based GFEM (V-GFEM): optimal enrichment for transient problems 

    Canales, Diego; Leygue, Adrien; Chinesta Soria, Francisco; González Ibáñez, David; Cueto Prendes, Elias; Feulvarch, Eric; Bergheau, Jean-Michel; Huerta, Antonio (2016-11)
    Article
    Accés restringit per política de l'editorial
    This paper proposes a generalized finite element method based on the use of parametric solutions as enrichment functions. These parametric solutions are precomputed off-line and stored in memory in the form of a computational ...
  • Real-time simulation techniques for augmented learning in science and engineering 

    Quesada, C.; González, D.; Alfaro, Icíar; Cueto Prendes, Elias; Huerta, Antonio; Chinesta, Francisco (Springer, 2016-11)
    Article
    Accés restringit per política de l'editorial
    In this paper we present the basics of a novel methodology for the development of simulation-based and augmented learning tools in the context of applied science and engineering. It is based on the extensive use of model ...
  • Optimizing mesh distortion by hierarchical iteration relocation of the nodes on the CAD entities 

    Ruiz Gironés, Eloi; Roca Navarro, Francisco Javier; Sarrate Ramos, Josep (2014-08)
    Article
    Accés obert
    Mesh untangling and smoothing is an important part of the meshing process to obtain high-quality discretizations. The usual approach consists on moving the position of the interior nodes while considering fixed the position ...
  • Adaptividade e estimativas de erro orientadas por metas aplicadas a um benchmark test de propagação de onda 

    Steffens, Lindaura; Díez, Pedro; Parés Mariné, Núria; Alves, Marcelo Krajnc (2016-01-12)
    Article
    Accés obert
    O objetivo deste artigo é estudar a eficiência e a robustez de técnicas adaptativas e estimativas de erro orientadas por metas para um benchmark test. As técnicas utilizadas aqui são baseadas em um simples pós-processo das ...
  • Un método de captura de choques basado en las funciones de forma para Galerkin discontinuo de alto orden 

    Casoni Rero, Eva; Peraire Guitart, Jaume; Huerta, Antonio (2012)
    Article
    Accés obert
    En este artículo se presenta un método de alto orden de Galerkin discontinuo para problemas de flujo com- presible, en los cuales es muy frecuente la aparición de choques. La estabilización se introduce mediante una nueva ...
