Open channel flow request
Could you describe how to do an open channel flow analysis, this can be done with multi phase method and interFoam solver but I have no experience with that. I would like to obtain turbulent velocity profile in a 10x10x400 m channel with velocity inlet speed od 1 m/s.Is it possible to get a velocity profile like in this article?https://www.brainkart.com/article/Velocity-distribution-in-open-channels_3491/I tried a lot of variations using simpleFoam and k-epsilon and k-omega method but my velocity profile stays uniform like in the picture. https://we.tl/t-7G28jTgIJnThank you for the tutorials, you're doing great work, keep it up!
