Abstract
Different sensors that provide a measure for the resolution of the LES content in hybrid RANS/LES computations are proposed and investigated. In an apriori test on isotropic turbulence a suitable sensor is identified. Based on that sensor an automatic local mesh refinement is performed for an IDDES of the flow over a backward facing step. The results obtained on locally adapted grids are compared to results on globally refined grids. It is shown, that the proposed sensors can detect underresolved LES regions and that the local mesh refinement can help to reduce resolution errors caused by a too coarse grid spacing.
