The formulation makes use of splitting methods, which means that it can be wrapped around an existing time-stepping code as a “black box.” The method is first applied to a scalar problem in order to analyse its stability and highlight the roles of the control coefficient χ and the filter width Δ in the convergence (or not) towards the steady-state. Then the steady-state of the incompressible flow past a two-dimensional cylinder at Re = 100, obtained with a code which implements the spectral/hp element method, is presented.
