HEC-RAS Tutorial 4 simulation of broad-crested weir (inline structure)

[@gabrielmendes4045]

When i try to create the inline structure in reach 1 station 10 comes a message: "Warning - a node already exists on reach 1 at river station "10". I already try to create at all my stations and the software didn't allowed. How can i fix this?

the flow is not blocked at the structure, the flow is same on and after the weir. why is it so?

Hello Users, I just need some insights on Breaklines. I have added breaklines into the 2d mesh area and enforced them as internal connections and entered weir data as top spillway elevation at 700m to the connections assuming they are acting as Embankments/weirs to the reservoir. But After I ran the Unsteady flow model successfully, in the results section in the RAS Mapper Water still flowing over the embankments at 653.55 only without filling the reservoir up to 700m elevation. What Should I do? Thank you in Advance #HECRAS #2dMODELING
