I don't think it's an error as such as a physics problem. Water enters the domain, so has a velocity and the boundary pressure is altered to give the flow: that's correct on the boundary. Water then accelerates due to gravity, again all good. The question (and where I need to be careful as Ansys staff because of the Forum rules) is how the solver deals with the cell-inlet interaction as the water next to the inlet is moving faster than the inlet velocity is set. n
