AB - We present an alternative “encapsulated” formulation of the selective frequencydamping method for finding unstable equilibria of dynamical systems, which isparticularly useful when analysing the stability of fluid flows. The formulation makesuse of splitting methods, which means that it can be wrapped around an existingtime-stepping code as a “black box.” The method is first applied to a scalar problemin order to analyse its stability and highlight the roles of the control coefficient χand the filter width in the convergence (or not) towards the steady-state. Then thesteady-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.
