Hi @all,
so i tried a few more simulations runs with different Solver and boundary conditions, unfortunately it also dosent work.
I think i get good results with the following boundary setup. Einlauf Velocity inlet 1,5 m/s; Auslauf unten Velocity outlet 1,5 m/s; Auslauf oben Pressure outlet (usally the Water dont get to it).
But an Error occured at 99% ;(.
After that i tried different Solvers, this ist the template for it, but it also dosent work well.
