Combining p-multigrid and multigrid reduction in time methods to obtain a scalable solver for isogeometric analysis

HIGHLIGHTS

  • who: Roel Tielen from the (UNIVERSITY) have published the research: Combining p-multigrid and Multigrid Reduction in Time methods to obtain a scalable solver for Isogeometric Analysis, in the Journal: (JOURNAL)
  • what: The authors combine the parallel-in-time Multigrid Reduction in Time method with a p-multigrid method to obtain a scalable solver specifically designed for Isogeometric Analysis. As a first step, the authors compare the number of MGRIT iterations to reach convergence when a p-multigrid method or a (diagonally preconditioned) Conjugate Gradient method is adopted while keeping all other parameters the same . . .
