Hello! Does anyone worked with free surface cannel flows? I have to simulate a flow of water in a channel with a free surface. Above is air. I have never done this and I would appreciate any help from you. Thank you

Use VOF multiphase flow for that. try implicit VOF first and when you get a good result switch to VOF geo-reconstruct for better interface shape

Cheers Amir

Thank you Amir! I'll try that way. I must say that I have never VOF method but I hope that I'll manage it. Maybe I'll come with others questions, if you don't mind. Best regards, Tiberiu
