  • Combining size-preserving and smoothing procedures for adaptive quadrilateral mesh generation 

    Ruiz Gironés, Eloi; Roca Navarro, Xevi; Sarrate Ramos, Josep (Springer, 2013)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    It is well known that the variations of the element size have to be controlled in order to generate a high-quality mesh. Hence, several techniques have been developed to limit the gradient of the element size. However, the ...
  • Inserting curved boundary layers for viscous flow simulation with high-order tetrahedra 

    Gargallo Peiró, Abel; Roca Navarro, Xevi; Sarrate Ramos, Josep; Peraire Guitart, Jaume (Springer, 2013)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    We propose an a posteriori approach for generating curved meshes for viscous flow simulations composed by high-order tetrahedra. The proposed approach is performed in the following three steps: (1) generate a linear ...
  • Defining quality measures for validation and generation of high-order meshes 

    Gargallo Peiró, Abel; Roca Navarro, Xevi; Peraire Guitart, Jaume; Sarrate Ramos, Josep (Springer, 2013)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    A procedure to quantify the distortion (quality) of a high-order mesh composed by curved tetrahedral elements is presented. The proposed technique has two main applications. First, it can be used to check the validity and ...
  • Generation of curved high-order meshes with optimal quality and geometric accuracy 

    Ruiz Gironés, Eloi; Sarrate Ramos, Josep; Roca Navarro, Xevi (Elsevier, 2016)
    Text en actes de congrés
    Accés obert
    We present a novel methodology to generate curved high-order meshes featuring optimal mesh quality and geometric accuracy. The proposed technique combines a distortion measure and a geometric L2-disparity measure into a ...
  • Integral microalgae-bacteria model (BIO_ALGAE): application to wastewater high rate algal ponds 

    Solimeno, Alessandro; Parker, Lauren; Lundquist, Tryg; García Serrano, Joan (2017-12)
    Article
    Accés restringit per política de l'editorial
    An integral mechanistic model describing the complex interactions in mixed algal-bacterial systems was developed. The model includes crucial physical, chemical and biokinetic processes of microalgae as well as bacteria in ...
  • Assessing the fairness of a Project Financing Formula on successive generations 

    Penyalver, Domingo; Turro Calvet, Mateo (2017-01)
    Article
    Accés restringit per política de l'editorial
    Major transport projects are appraised mostly through cost-benefit analysis. In practice, though, decision-making takes into account many other aspects that are more. or less political. When properly defined, they may be ...
  • Interpolation with restrictions between finite element meshes for flow problems in an ALE setting 

    Pont Ribas, Arnau; Codina, Ramon; Baiges Aznar, Joan (John Wiley & Sons, 2017-06)
    Article
    Accés restringit per política de l'editorial
    The need for remeshing when computing flow problems in domains suffering large deformations has motivated the implementation of a tool that allows the proper transmission of information between finite element meshes. Because ...
  • The RockRisk project: rockfall risk quantification and prevention 

    Corominas Dulcet, Jordi; Lantada Zarzosa, Maria de Las Nieves; Gili Ripoll, José Antonio; Ruiz Carulla, Roger; Matas Casado, Gerard; Mavrouli, Olga Christina; Núñez Andrés, María Amparo; Moya Sánchez, José; Buill Pozuelo, Felipe; Abellán Fernández, Antonio; Puig i Polo, Càrol; Prades Valls, Albert; Martínez Bofill, Joan; Salo Salgado, Lluis (Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Rockfalls are frequent instability processes in road cuts, open pit mines and quarries, steep slopes and cliffs. The orientation and persistence of joints within the rock mass define the size of the kinematically unstable ...
  • Rockfall fragmentation analysis: Vilanova de Banat case study 

    Matas Casado, Gerard; Lantada Zarzosa, Maria de Las Nieves; Corominas Dulcet, Jordi; Gili Ripoll, José Antonio; Ruiz Carulla, Roger; Prades Valls, Albert (Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2017)

    Fragmentation is a critical mechanism for the calculation of the trajectories of the blocks and the impact energies, for the assessment of the potential damage and for the design of protec-tive structures, although few ...
  • Assessment of green measures as coastal defences using numerical models 

    Sánchez-Arcilla Conejo, Agustín; García León, Manuel; Gracia Garcia, Vicente; Sierra Pedrico, Juan Pablo (2017)
    Text en actes de congrés
    Accés obert
    Climate change may reduce the performance and design life of “grey” coastal engineering interventions. Green solutions can be combined with present infrastructures providing extra flexibility to adapt our present beaches ...
