12.20.4 Large Eddy Simulation Model

It is possible to specify the magnitude of random fluctuations of the velocity components at an inlet only if the velocity inlet boundary condition is selected. In this case, you must specify a Turbulence Intensity that determines the magnitude of the random perturbations on individual mean velocity components as described in Section  12.9.4. For all boundary types other than velocity inlets, the boundary conditions for LES remain the same as for laminar flows.
