Steady-state computations based on RANS (Reynolds-Averaged Navier-Stokes) are the common approach for computing airfoil polars. The workflow at Fraunhofer IWES is fully automated and the turbulence models are optimized for good force prediction, including stall and at high Reynolds numbers. Transition models are also available. Please find hereafter a few images to illustrate these methods. Furthermore, an example case for airfoil simulations can be found on Fraunhofer Gitlab webpage.
