Hi everybody,

I am performing a hydrodynamic simulation including two inlets and one outlet. So in my open boundary file I have considered T Q(1) Q(2) SL(3) and the numbers are related to the order of boundaries in .cli file. The program is running without any problem and the values printed for SL(3) in the graphical printout are exactly as same as the values in open boundary file. However the results are showing some other values at the nodes which are located in the outlet while it should be similar to the values introduced in open boundary file. Why it is not following my open boundary file???
I have attached my .cli file and the .qsl file here.

Thank you so much in advance.

Hello

This could happen if your outlet is getting super critical. If it is the case, modify yur geometry (or bathymetry/or ...) in order to keep subcritical regime there.
kind regards
