    • Explicit-in-Time Goal-Oriented Adaptivity 

      Muñoz-Matute J.; Calo V.M.; Pardo D.; Alberdi E.; Van der Zee K.G. (Computer Methods in Applied Mechanics and Engineering, 2019-04-15)
      Goal-oriented adaptivity is a powerful tool to accurately approximate physically relevant solution features for partial differential equations. In time dependent problems, we seek to represent the error in the quantity of ...
    • Goal-oriented adaptivity using unconventional error representations for the 1D Helmholtz equation 

      Darrigrand V.; Pardo D.; Muga I. (Computers and Mathematics with Applications, 2015-12-31)
      In this work, the error of a given output functional is represented using bilinear forms that are different from those given by the adjoint problem. These representations can be employed to design novel h, p, and hp ...
    • Quantities of interest for surface based resistivity geophysical measurements 

      Alvarez-Aramberri J.; Bakr S.A.; Pardo D.; Barucq H. (Procedia Computer Science, 2015-12-31)
      The objective of traditional goal-oriented strategies is to construct an optimal mesh that minimizes the problem size needed to achieve a user prescribed tolerance error for a given quantity of interest (QoI). Typical ...
    • Simulation of marine controlled source electromagnetic measurements using a parallel fourier hp-finite element method 

      Pardo D.; Nam M.J.; Torres-Verdín C.; Hoversten M.G.; Garay Iñ. (Computational Geosciences, 2011-12-31)
      We introduce a new numerical method to simulate geophysical marine controlled source electromagnetic (CSEM) measurements for the case of 2D structures and finite 3D sources of electromagnetic (EM) excitation. The method ...
