The paper compares two dierent two-grid ยฎnite element formulations applied to the NavierยฑStokes equations, namely a multigrid and a mixed or composite formulation. In the latter case the pressure is interpolated on a coarser grid than the velocity, using mixed elements instead of mixed interpolation
## Abstract A new formulation of the NavierโStokes equations is introduced to solve incompressible flow problems. When finite element methods are used under this formulation there is no need to worry whether BabuskaโBrezzi condition is satisfied or not. Both velocity and pressure can be obtained se
