Elimination of Curvature-Induced Grid Motion for \(r\)-Adaptation
Using an adaptive method in the context of a large eddy simulation (LES) is rarely seen in literature. A challenging aspect for this combination is the interplay between the resolution of the grid and the governing equations to be solved, since the grid spacing defines the scale separation between the resolved large-scale turbulent fluctuations and the unresolved subgrid-scale turbulence, so that whenever the grid changes in time this decomposition changes as well.
