A precursor boundaryFoam
calculation is used to set the inlet flow conditions onto which turbulent content is superimposed using the turbulentDFSEMInlet
velocity condition.

The following images show examples of the instantaneous- and mean-velocity predictions
Profiles at a series of x/h positions are presented in the following images, where the predictions are compared against the experimental data of Martinuzzi and Tropea [49]
