    • Refined Isogeometric Analysis for a Preconditioned Conjugate Gradient Solver 

      Garcia D.; Pardo D.; Dalcin L.; Calo V.M. (Computer Methods in Applied Mechanics and Engineering, 2018-06-15)
      Starting from a highly continuous Isogeometric Analysis (IGA) discretization, refined Isogeometric Analysis (rIGA) introduces $C^0$ hyperplanes that act as separators for the direct LU factorization solver. As a result, ...
    • 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) ...
