Hi,
After an instant load rejection run, I'm getting an error message, "The root sought is not obtained to iteration 2" on the surge tank. What does this mean?
Thanks.
Jace
Hi Jason,
This may be related to the inlet headloss problem discussed in your other thread. If you're still seeing this, try using a smaller timestep (or if the timestep is too small, try something closer to 0.01 seconds).
Also, check your HAMMER version and upgrade to the latest version (10.03.01.08) if possible and if your version is older. You can find your version number under File > Help > About.
If you need further help, please provide a copy of the model for review: Sharing Hydraulic Model Files on the OpenFlows Forum

Thanks Jesse.
Yes, the issue has been resolved as well when I made the change in the surge tank diameter as mentioned in my other thread.
