Hi all,
am struggling with this problem at the moment. So I’m doing a full 2d modelling. There is a weir/dam in the middle of my study area. I inserted 2 gates to this dam. When I start the simulation, even though the inflow boundary condition is far away and water should not reach the dam yet, there is a water flowing out of my gates (near my dam). I can’t seem to understand how this is possible. If anyone has experienced and knows how to solve it, I would highly appreciate that.
