I have developed a model for a project that I am working on. It is a small but complicated model. I have 3 structures with 2 chambers and have weirs and orifices between the chambers. when I ran the model for 100 year storm and look at the animation, weirs go crazy with zillion peaks. I am not sure why weirs are so unstable. Can anyone please suggest any solution? I have attached the model here.
Thanks,
KD
You could try to increase your time step. Just don't go crazy with it or you could miss your true peak if the time step is too large.
Matt, Do you mean reducing the routing time under "Analysis Options"? Currently I have it set at 30 sec (default value).
Yes, reduce the hydraulic routing time step in Analysis options.
