    • Direct solvers performance on h-adapted grids 

      Paszynski M.; Pardo D.; Calo V.M. (Computers and Mathematics with Applications, 2015-12-31)
      We analyse the performance of direct solvers when applied to a system of linear equations arising from an $h$-adapted, $C^0$ finite element space. Theoretical estimates are derived for typical $h$-refinement patterns arising ...
