Hello everyone !

I am trying to model a flow over a spillway ( with an extra aerator). I have already model a 2D version of the problem in order to familiarize myself with the VOF method. However, despite the convergence of my result the answer does not seem "realistic"

Here is pictures of my patch and the results





I was expecting an hydraulic jump in the stilling but my flow keep accelerating until the outlet and the water depth is way below of what it should be (I have the same result withoud water in the stilling bassin)

I think it is a problem of BC at the outlet, here is my BC :
- Pressure outlet
- Flow normal to boundary
- Open channel : Free surface level and neighboring cell volume fraction (I have also try specified free surface level without any change)

I am also using the realizable ke model.

Thanks for your help or any suggestion
Best regards
