i need to simulate a stream flowing off a lake. the first reach stream's slope is negative. there are a duct that discharge in the stream in the same direction of the stream's flow. The negative slope produces that the total entering discharge is bigger then the outlet discharge so there is a part of the flow that turns back to the lake. must i give two outlet boundary conditions? must i use the VOF method? i thank anyone could help me giving me some information about the best way to simulate this case with fluent. many thanks Marco

about my previous message obviously my first question is if is fluent an adecuate software to simulating the case I exposed for eventually ask the university if they have this software available thanks Marco
