    We demonstrate a reconfigurable virtual datacenter network by utilizing statistical multiplexing offered by scalable and flow-controlled optical switching system. Results show QoS guarantees by the priority assignment and ...
  • Dimensional hyper-reduction of nonlinear finite element models via empirical cubature 

    Hernández Ortega, Joaquín Alberto; Caicedo Silva, Manuel Alejandro; Ferrer Ferré, Àlex (2017-01)
    Article
    Open Access
    We present a general framework for the dimensional reduction, in terms of number of degrees of freedom as well as number of integration points (“hyper-reduction”), of nonlinear parameterized finite element (FE) models. The ...

  • On multi-scale structural topology optimization and material design 

    Ferrer Ferré, Àlex; Cante Terán, Juan Carlos; Oliver Olivella, Xavier (Associação Portuguesa de Mecânica Teórica, Aplicada e Computacional (APMTAC), 2015)
    Conference report
    Restricted access - publisher's policy
    Computational material design has gained considerable interest, along the last years, in the computational mechanics community. Although most of the current approaches focus on one-scale structural optimization, this work ...
  • The domain interface method in non-conforming domain decomposition multifield problemsdomain decomposition multifield problems 

    Lloberas Valls, Oriol; Cafiero, Mailhyn E.; Cante Terán, Juan Carlos; Ferrer Ferré, Àlex; Oliver Olivella, Xavier (2016-12)
    Article
    Open Access
    The Domain Interface Method (DIM) is extended in this contribution for the case of mixed fields as encountered in multiphysics problems. The essence of the non-conforming domain decomposition technique consists in a ...
  • Topological sensitivity analysis in heterogeneous anisotropic elasticity problem: theoretical and computational aspects 

    Giusti, Sebastian Miguel; Ferrer Ferré, Àlex; Oliver Olivella, Xavier (2016-11)
    Article
    Restricted access - publisher's policy
    The topological sensitivity analysis for the heterogeneous and anisotropic elasticity problem in two-dimensions is performed in this work. The main result of the paper is an analytical closed-form of the topological ...
  • Two-scale topology optimization in computational material design: an integrated approach 

    Ferrer Ferré, Àlex; Cante Terán, Juan Carlos; Hernández Ortega, Joaquín Alberto; Oliver Olivella, Xavier (John Wiley & Sons, 2018-01)
    Article
    Open Access
    In this work, a new strategy for solving multiscale topology optimization problems is presented. An alternate direction algorithm and a precomputed offline microstructure database (Computational Vademecum) are used to ...
  • Vademecum-based approach to multi-scale topological material design 

    Ferrer Ferré, Àlex; Oliver Olivella, Xavier; Cante Terán, Juan Carlos; Lloberas Valls, Oriol (Springer, 2016-12)
    Article
    Open Access
    The work deals on computational design of structural materials by resorting to computational homogenization and topological optimization techniques. The goal is then to minimize the structural (macro-scale) compliance by ...
