Torben,

Thank for your quik response.
The problem of branches is solved thanks to your help. I didn't need side structure, so i removed them.

The problem of stability stay. I verified that structures make a contraction with a head-loss in the river thank to the plot.
In attach file you can find the differents files of model.
Do you hane an idea for the cause of instabilities ?

Thanks,
SCPsho

Hi everyone,

I have problems with Mike11.
- It creates two branches (surround in attach file) which do not exist in my source files (overview network). I would like to delete them and unterstand why it puts these branches.
- After many unsuccessful trials, the result is unstable in structures despite of a constant flow and a low time step (10 sec).

Do you have any idea why this might be?

Thanks,
SCPsho
