✦ Synopsis

This paper studies the e ciency of two ways to treat the non-linear convective term in the timedependent incompressible Navier-Stokes equations and of two multigrid approaches for solving the arising linear algebraic saddle point problems. The Navier-Stokes equations are discretized by a secondorder implicit time stepping scheme and by inf-sup stable, higher order ÿnite elements in space. The numerical studies are performed at a 3D ow around a cylinder.
