A geometric multigrid method for isogeometric compatible discretizations of the generalized Stokes and Oseen problems

Summary In this paper, we present a geometric multigrid methodology for the solution of matrix systems associated with isogeometric compatible discretizations of the generalized Stokes and Oseen problems. The methodology provably yields a pointwise divergence‐free velocity field independent of the n...
