mike hydro river

I need to couple a mike hydro river model with my mike she model.
Everytime I try to run the mike hydro river model, it gives the error of "EN_ERR_OpenBndMissing" ''<River name>', 0' is defined as an open boundary in the model, however no open boundary is defined.
Please let me know what can I do to resolve this.

Hi Hamna

My guess would be that you have a boundary defined under Standard Boundaries and this is located at a chainage that is outside of the chainage of your branch.

Hope this makes sense
