Since wall-resolved LES suffers from very fine near-wall grid resolutions required (\(\varDelta y_{1st}^+ < 2\), \(\varDelta x^+\) = \({\fancyscript{O}}\)(50–150), \(\varDelta z^+\) = \({\fancyscript{O}}\)(15–40)), the idea to embed a near–wall (U)RANS region within a LES represents both, a specific type of hybrid approach and an enhanced kind of wall model.
