  A Multigrid Solver for the Navier-Stokes Equations Using Divergence-free Block-Iteration
Vincent Heuveline (Univ. Karlsruhe)

(joint work with F. Schieweck)

We propose a new multigrid method for solving the Navier-Stokes equations on quadrilateral or hexahedral meshes by means of the higher order finite elements pairs (Qk,Pk-1disc) for k≥2. Our approach is based on a block smoother where the blocks are defined by means of the divergence-free basis of finite elements related to the considered pair (Qk,Pk-1disc). Numerical tests validate the proposed approach.
