The importance of numerical models to predict the behavior of physical systems grows continuously. Suitable mathematical models combined with powerful numerical methods have become indispensable to make accurate predictions. The objective of the Workshop on Numerical Methods in Applied Sciences and Engineering is to foster the research in this area, and promote the international relations and collaboration of different research groups. The workshop is devoted to both basic methods and industrial implementations and applications. Sessions related to specific topics will be introduced by a keynote lecture.

  • Strict error bounds in linear solid mechanics using a subdomain-based flux-free approach 

    Cottereau, Regis; Díez, Pedro (2009-06-08T11:56:46Z)
    Conference report
    Open Access
    In this paper, we derive, in the framework of the ux-free method, strict bounds for the energy norm of the error associated to a finite element computation. In that framework, and when using linear elements, the problems ...
  • The block gauss-seidel method in sound transmission problems 

    Poblet-Puig, Jordi; Rodríguez Ferran, Antonio (2009-06-08T11:23:31Z)
    Conference report
    Open Access
    Sound transmission through partitions can be modelled as an acoustic fluid-elastic structure interaction problem. The block Gauss-Seidel iterative method is used in order to solve the finite element linear system of ...
  • Simple assessment of the numerical wave number in the fe solution of the helmholtz equation

    Conference report
    Open Access
    When numerical methods are applied to the computation of stationary waves, it is observed that "numerical waves" are dispersive for high wave numbers. The numerical wave shows a phase velocity which depends on the wave ...

    Muñoz, José J.; Bonet Carbonell, Javier; Huerta, Antonio; Peraire Guitart, Jaume (2009-06-08T10:28:14Z)
    Conference report
    Open Access
    In the present paper we compute upper and lower bounds for limit analysis in two and three dimensions. From the solution of the discretised upper and lower bound problems, and from the optimum displacement rate and stress ...
  • 3D nurbs-enhanced finite element method 

    Sevilla Cárdenas, Rubén; Fernandez Mendez, Sonia; Huerta, Antonio (2009-06-08T10:12:04Z)
    Conference report
    Open Access
    An improvement of the classical finite element method is proposed in [1], the NURBS-Enhanced Finite Element Method (NEFEM). It is able to exactly represent the geometry by means of the usual CAD description of the boundary ...
  • Acoplamiento del modelo regional de calidad de aire (CMAQ) con el modelo de emisiones locales mediante elementos finitos 

    Pérez Foguet, Agustí; Oliver Serra, Albert (2009-06-08T09:47:57Z)
    Conference report
    Open Access
    Existen modelos regionales de calidad del aire que son muy utilizados. Estos modelos tienen modelos para estudiar el aporte de contaminantes provocados por fuentes importantes de contaminación, como pueden ser chimeneas, ...

    Huerta, Antonio; Casoni, Eva (2009-06-08T08:32:41Z)
    Conference report
    Open Access
    A shock capturing strategy for high order Discontinuous Galerkin methods for conservation laws is proposed. We present a method in the one-dimensional case based on the introduction of artificial viscosity into the ...

    Conference report
    Open Access
    In this paper we present an object oriented implementation of a general-purpose mesh generation environment for geometry-based simulations. The aim of this application is to unify available legacy code and new research ...
  • A critical comparison of two discontinuous galerkin methods for the navier-stokes equations using solenoidal aproximations 

    Villardi de Montlaur, Adeline de; Peraire Guitart, Jaume; Huerta, Antonio (2009-06-08T07:49:26Z)
    Conference report
    Open Access
    This paper compares two methods to solve incompressible problems, in particular the Navier-Stokes equations, using a discontinuous polynomial interpolation that is exactly divergence-free in each element. The first method ...
