Yes I did type uniform in the input file.

for the free surface I kind figure it out.

I'm gonna try and find something about the kOmega model, do you have any link that I can start with ?

Thank you for your help

Here's some issues people have helped me with for internal flow:

    inlet
    {
        type            turbulentIntensityKineticEnergyInlet;
        intensity       0.05;
        value           uniform 60;
    }

Hi, do you know how to calculate the initial value? here you make the initial value to be "uniform 60"

If you know approximate values of average velocity OR some Initial guess/rough calculations, you can use the formulae below for k and Epsilon.

Hope that helps.
