Strange behaviour of the water flume
I am currently modeling on a water flume. But the calculation shows a strange behaviour. To get to the reason for this, I built a physical 1:6 model and simulated the "numerical experiment". I know my physical model is not perfect, because of the friction an it's also not totally horizontal... But for me I thought it would be good to see if the two model gave me results in the same direction.
In the physical model the flume is filled over the whole width. In the numerical model everything comes together in the middle!?
Does anyone have an idea where the error in my case definition could be?
Many thanks in advance
