Hi every one!
I want to model a 3d open channel, using openfoam. Would anyone please tell me, what kind of boundary face I should use for the free surface?
Thanks a lot.

You don't have to define the free surface ,just use the "setFieldsDict".And please remember to keep the Co Number <0.5(to get a better trace of the free surface).
