    • A 2D numerical model for the transport of pollutants. The influence of Boundary Conditions 

      Bonillo Martínez, Juan José; Fe, Jaime; Vellando, Pablo; Puertas, Jerónimo (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 minimum weight FEM formulation for Structural Topological Optimization with local stress constraints 

      París, José; Muíños Pantín, Iago; Navarrina, Fermín; Colominas, Ignasi; Casteleiro, Manuel (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. ...

    • High order shape design sensitivity: an unified approach 

      Navarrina, Fermín; López Fontán, Santiago; Colominas, Ignasi; Bendito Pérez, Enrique; Casteleiro, Manuel (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. ...

    • Structural topology optimization with high spatial definition by using the overweight approach 

      Villalba Rama, Diego; París, José; Couceiro, Iván; Navarrina, Fermín (WIT Press, 2022)
      [Abstract:] The first formulation of topology optimization was proposed in the 1980s. Since then, many contributions have been presented with the purpose of improving its efficiency and expanding its field of application. ...
