    • 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, ...
