I am trying to model a bridge with an overflow area. When the model gets to a high flow, I get the following note: “For the cross section inside the bridge at the upstream end, the water surface and energy have been projected from the upstream cross section. the selected bridge modeling method does not compute answers inside the bridge.” This effectively shuts down the flow through the bridge, forces most of the flow over the roadway and drives my water surface up. Has anyone run into this and does anyone have any advice?
