    • An adaptive choice of primal constrains for BDDC domain decomposition algorithms 

      Calvo Alpízar, Juan Gabriel; Widlund, Olof B. (2016-12-12)
      An adaptive choice for primal spaces based on parallel sums is developed for BDDC deluxe methods and elliptic problems in three dimensions. The primal space, which forms the global, coarse part of the domain decomposition ...
    • Domain Decomposition Methods for Problems in H(curl) 

      Calvo Alpízar, Juan Gabriel (2015-05)
      Two domain decomposition methods for solving vector field problems posed in H(curl) and discretized with Nedelec finite elements are considered. These finite elements are conforming in H(curl). A two-level overlapping ...
    • Parallel Sums and Adaptive BDDC Deluxe 

      Widlund, Olof B.; Calvo Alpízar, Juan Gabriel (2017)
      There has recently been a considerable activity in developing adaptive methods for the selection of primal constraints for BDDC algorithms and, in particular, for BDDC deluxe variants. The primal constraints of a BDDC or ...
