Weir elevation

[Anonymous]

Hello there !

I’m working on 2D modelling, and i have some bridge on my model.

To build the bridge i’m using SA/2D connection but when i wan’t to start simulation, i have this problems :

Any solutions ? Where i can see weir elevation and modify this ?

Thanks a lot for your answers !!

Have a great day

Your weir elevation cannot be lower than the cell elevation. Your weir elevation is about 3 times smaller than the cell elevation. Probably metric to English units conversion error.

Hello Cameron,

Thanks a lot for your reply,

How can i resolve this error ?

[Anonymous]

I tried to convert the data with the good units but I still have the same problem .. Any solutions ?

Thanks for reply !

In the connection editor there is a button that says clip weir to 2D cells. That will fix it.

Hello,

I tried to use the button ”Clip weir profile to 2D Cells” with a number of 0.2 but it still doesn’t work ..

I have the same error :

For the Hydraulic Structure
in 2D area Perimeter 3
there is a gate or culvert that is outside of the weir stationing

Thanks for your time !
