We use a stabilized FEM with Gear time‐stepping to study periodically forced internal flows. The time‐periodically forced Navier‐Stokes equations always admit a time‐periodic solution but we show that this time‐periodic solution might not be stable, even in 2‐D. Numerical results are presented for a time‐periodic lid driven cavity. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
