    • Forward-in-Time Goal-Oriented Adaptivity 

      Muñoz-Matute J.; Pardo D.; Calo V.M.; Alberdi E. (International Journal for Numerical Methods in Engineering, 2019-03)
      In goal-oriented adaptive algorithms for partial differential equations, we adapt the finite element mesh in order to reduce the error of the solution in some quantity of interest. In time-dependent problems, this adaptive ...
    • Goal-oriented adaptivity using unconventional error representations for the multi-dimensional Helmholtz equation 

      Darrigrand V.; Rodríguez-Rozas A.; Muga I.; Pardo D.; Romkes A.; Prudhomme S. (International Journal for Numerical Methods in Engineering, 2017-06-27)
      In goal‐oriented adaptivity, the error in the quantity of interest is represented using the error functions of the direct and adjoint problems. This error representation is subsequently bounded above by element‐wise error ...
    • Time-Domain Goal-Oriented Adaptivity Using Pseudo-Dual Error Representations 

      Muñoz-Matute J.; Alberdi E.; Pardo D.; Calo V.M. (Computer Methods in Applied Mechanics and Engineering, 2017-12)
      Goal-oriented adaptive algorithms produce optimal grids to solve challenging engineering problems. Recently, a novel error representation using (unconventional) pseudo-dual problems for goal-oriented adaptivity in the ...
