Yes I have a SA/2D connection with a culvert and a weir. The plot stage hydrograph is empty i don’t know why… There isn’t a table like for 1D to know the hydraulic caracteristic in the culvert and in the weir?
Perhaps I don’t understand but when you have drawn your SA/2D connection and you apply the “enforce internat connection as breakline” option, the vertex just touch the face of the cell…
