    • Computational cost estimates for parallel shared memory isogeometric multi-frontal solvers 

      Wozniak, M.; Kuznik, K.; Paszynski, M.; Calo, V.M.; Pardo, D.Autoridad BCAM (2014-12-31)
      In this paper we present computational cost estimates for parallel shared memory isogeometric multi-frontal solvers. The estimates show that the ideal isogeometric shared memory parallel direct solver scales as $\mathcal{O}( ...
    • Computational cost of isogeometric multi-frontal solvers on parallel distributed memory machines 

      Wozniak, M.; Paszynski, M.; Pardo, D.Autoridad BCAM; Dalcin, L.; Calo, V.M. (2015-12-31)
      This paper derives theoretical estimates of the computational cost for isogeometric multi-frontal direct solver executed on parallel distributed memory machines. We show theoretically that for the $C^{p-1}$ global continuity ...
    • Parallel refined Isogeometric Analysis in 3D 

      Siwik, L.; Wozniak, M.; Trujillo, V.; Pardo, D.Autoridad BCAM; Calo, V.M.; Paszynski, M. (2018-11)
      We study three-dimensional isogeometric analysis (IGA) and the solution of the resulting system of linear equations via a direct solver. IGA uses highly continuous $C^{p-1}$ basis functions, which provide multiple benefits ...
