“…A discrepancy of 15 counts was computed, i.e a 6.2% error. Menter et al [31] computed a Wall-Function LES on the Notchback DrivAer using GPU solver over two grids made of 250 and 500 million cells. The use of wall function allowed the authors to use a grid with y + > 30 and then focused on wake resolution rather than boundary layer resolution.…”
