This work investigates the sensitivity of LES to a rotation of the usual stream-aligned system of coordinates in the case of channel flow at Re τ = 180. In the new reference system the principal axes are not necessarily aligned with the streamwise and the spanwise directions: consequently the mean pressure gradient has two different components. Two different codes and different SGS models have been tested in order to evaluate the sensitivity of the alignment of the grid with the mean stream and the coherent wall structures.
