The method is based on the work of [#xie2008 Xie and Castro (2008)] and [#kim2013 Kim et al. (2013)]. Unscaled turbulent motions ''u,,*j,,'' are computed based on length scales along each direction and the amplitude tensor ''a,,ij,,'' which in turn bases on the Reynolds stress tensor. The calculated turbulence is then added to the mean inflow data of the velocity components ''U,,i,,'': 502 503 {{{
