A local preconditioning technique for compressible flows at low Mach numbers is examined in the context of turbulent flows over multi-element high-lift airfoils. Numerical results obtained indicate that the local preconditioning method can improve the convergence to a steady state solution as well as the accuracy of the computed results.
