Summary
We introduce several multigrid smoothers for the incompressible Navier-Stokes equations in 2 space dimensions on unstructured grids and compare their performance for the DFG-bench markproblem of laminar flow around a cylinder depending on the kinematic viscosity. We further employ a streamwise numbering strategy of the unknowns and compare it to the hierarchical ordering the refinement module creates as well as to standard lexicographic numbering.
