Hi Foamers,

I have an open channel where I want to introduce a time series of flow rates from the inlet boundary and a specific discharge (which entered the channel) from the outlet boundary. Which boundary conditions should I use for the inlet and outlet to allow the flow to pass through without reflecting it (whether from downstream to upstream or vice versa)?

If I use the inletOutlet boundary for the outlet, I can not introduce a specific discharge for this boundary at the same time.

Thank you in advance,
Neshat
