    • The value of continuity: Refined isogeometric analysis and fast direct solvers 

      Garcia D.; Pardo D.; Dalcin L.; Paszynski M.; Collier N.; Calo V.M. (Computer Methods in Applied Mechanics and Engineering, 2016-09-23)
      We propose the use of highly continuous finite element spaces interconnected with low continuity hyperplanes to maximize the performance of direct solvers. Starting from a highly continuous Isogeometric Analysis (IGA) ...
    • Variational Formulations for Explicit Runge-Kutta Methods 

      Muñoz-Matute J.; Pardo D.; Calo V. M.; Alberdi E. (Finite Elements in Analysis and Design, 2019-08)
      Variational space-time formulations for partial di fferential equations have been of great interest in the last decades, among other things, because they allow to develop mesh-adaptive algorithms. Since it is known ...
    • Variational multiscale stabilization for compressible flow 

      Moragues Ginard M.; Vázquez M.; Houzeaux G. (Computer Methods in Applied Mechanics and Engineering, 2018)
      This paper presents a variational multiscale stabilization for the finite element numerical solution of the Euler and Navier-Stokes equations of compressible flow. All the components of the dual operator are considered in ...
