    • Optimally refined isogeometric analysis 

      Garcia D.; Bartoň M.; Pardo D. (Procedia Computer Science, 2017-06)
      Performance of direct solvers strongly depends upon the employed discretization method. In particular, it is possible to improve the performance of solving Isogeometric Analysis (IGA) discretizations by introducing multiple ...
    • 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, ...
