• A unified approach for high order sensitivity analysis 

      Navarrina, Fermín; Colominas, Ignasi; Juanes, Rubén; Bendito Pérez, Enrique; Casteleiro, Manuel (Computational Mechanics Publications, 2001)
      [Abstract] Many engineering problems require solving PDEs by means of numerical methods (type FEM/BEM) which sensivity analysis entails taking derivatives of functions defined through integration. In sizing optimization ...
    • 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. ...
