Hydraflow Constantly Crashes

I am running Civil 3D 2012 and my Hydraflow crashes everytime I run an analysis.  I am using a known Q and have input pipe inverts/slopes and pipe sizes.  Everytime I try running an analysis I get the following message:  Line 1, 2, 3 has no flow.  Check pipe size(s) and slope(s).  Then the program closes up.


Anyone have any suggestions?


Thank you in advance.

Please make sure you have SP 2.1 installed. We believe to have fixed this issue with Storm Sewers extension with the service pack. You can download and install from the following link:
